Crystal structure of a one-dimensional helical-type silver(I) coordination polymer: catena-poly[[silver(I)-μ-N-(pyridin-4-ylmeth-yl)pyridine-3-amine-κ(2) N:N'] nitrate dimethyl sulfoxide disolvate].

The asymmetric unit of the title compound, {[Ag(C11H11N3)]NO3·2(CH3)2SO} n , comprises one Ag(I) atom, one N-(pyridine-4-ylmeth-yl)pyridine-3-amine ligand, one nitrate anion and two dimethyl sulfoxide mol-ecules. The Ag(I) atoms are bridged by two pyridine N atoms from two symmetry-related ligands, forming a helical chain and adopting a slightly distorted linear coordination geometry [N-Ag-N = 175.37 (8)°]. The helical chain, with a pitch length of 16.7871 (8) Å, propagates along the b-axis direction. In the crystal, symmetry-related right- and left-handed helical chains are alternately arranged via Ag⋯Ag inter-actions [3.4145 (4) Å] and π-π stacking inter-actions [centroid-centroid distance = 3.650 (2) Å], resulting in the formation of a two-dimensional supra-molecular network extending parallel to (100). Weak Ag⋯O [2.775 (2), 3.169 (4) and 2.690 (2) Å] inter-actions, as well as several N-H⋯O and C-H⋯O hydrogen-bonding inter-actions, contribute to the stabilization of the crystal structure. Parts of the dimethyl sulfoxide solvent molecule are disordered over two sets of sites in a 0.937 (3):0.063 (3) ratio.

Chemical context

Self-assembled supra­molecular architectures based on the reaction of the silver ion with dipyridyl-type ligands continue to attract attention not only because of the fascinating structures caused by a variety of coordination geometries for the AgI cation, but also their potential applications as functional materials (Lee et al., 2012 ▶; Leong & Vittal, 2011 ▶; Park et al., 2010 ▶; Zhang et al., 2009 ▶, 2013 ▶). However, although there has been rapid growth in AgI coordination chemistry based on symmetrical dipyridyl ligands with nitro­gen donor atoms in the same positions on two terminal pyridines, investigations based on unsymmetrical dipyridyl ligands with nitro­gen donor atoms in different positions on two terminal pyridines are still rare (Moon & Park, 2013 ▶, 2014 ▶; Zhang et al., 2013 ▶). Therefore, the development of AgI coordination polymers using unsymmetrical dipyridyl ligands is a challenging project and deserves exploration. Herein, we report the crystal structure of the title compound prepared by the reaction of silver nitrate with the unsymmetrical dipyridyl ligand, N-(pyridin-4-ylmeth­yl)pyridine-3-amine, which was been synthesized by the reaction of 3-amino­pyridine and pyridine-4-carboxaldehyde according to literature methods (Foxon et al., 2002 ▶; Lee et al., 2013 ▶). The structure of the title compound is related to that of the monohydrated AgI coordination polymer with the same ligand (Zhang et al., 2013 ▶).

Structural commentary

The mol­ecular components of the title structure are shown in Fig. 1 ▶. The asymmetric unit consists of one AgI atom, one N-(pyridin-4-ylmeth­yl)pyridine-3-amine ligand, one nitrate anion and two DMSO mol­ecules. The S atom of one of the DMSO mol­ecules is disordered over two sites [site-occupancy factors of 0.937 (3) for S2 and 0.063 (3) for S2′]. The Ag atom links two pyridine N atoms from two symmetry-related ligands, forming a helical chain. Thus the AgI atom is two-coordinate in a slightly distorted linear coordination geometry [N—Ag—N = 175.37 (8)°], with the Ag—N bond lengths of 2.158 (2) and 2.162 (2) Å. The helical chain propagates along the b-axis direction (Fig. 2 ▶) and its pitch length is 16.7871 (8) Å, much longer than that [10.135 (2) Å] of the monohydrated AgI coordination polymer reported by Zhang et al. (2013 ▶). The two pyridine rings coordinating to the Ag atom are tilted by 9.77 (16)° with respect to each other. In the N-(pyridin-4-ylmeth­yl)pyridine-3-amine ligand, the two pyridine rings are almost perpendicular, the dihedral angle between their mean planes being 86.28 (7)°.

Supra­molecular features

In the crystal structure, the symmetry-related right- and left-handed helical chains are alternately arranged in the structure via Ag⋯Ag inter­actions [3.4145 (4) Å], resulting in the formation of a two-dimensional supra­molecular network extending parallel to (100) (Fig. 2 ▶). π–π stacking inter­actions [centroid–centroid distance = 3.650 (2) Å] between the pyridine rings of both helical chains contribute to the stabilization of the two-dimensional network. The two-dimensional networks are further stabilized by Ag⋯O inter­actions [Ag1⋯O1 = 2.775 (2), Ag1⋯O2i = 3.169 (4) and Ag1⋯O4 = 2.690 (2) Å; symmetry code: (i) −x + 1, −y + 1, −z] (Fig. 2 ▶), as well as N—H⋯O and C—H⋯O hydrogen bonds between the helical chains and the nitrate anions or the DMSO mol­ecules (Table 1 ▶). In addition, several C—H⋯O hydrogen bonds between the DMSO mol­ecules, and between the DMSO mol­ecules and the nitrate anions are also observed.

Database survey

The structures of the silver(I) nitrate and perchlorate complexes of the same ligand have been reported as their monohydrated and non-solvated forms, respectively, by Zhang et al. (2013 ▶). These complexes have been also studied for their luminescent properties in the solid state.

Synthesis and crystallization

N-(Pyridin-4-ylmeth­yl)pyridine-3-amine was prepared according to the procedure described by Lee et al. (2013 ▶) and Foxon et al. (2002 ▶). Crystals of the title compound suitable for X-ray analysis were obtained by vapour diffusion of diethyl ether into a DMSO solution of the white precipitate afforded by the reaction of the ligand with silver(I) nitrate in the molar ratio 1:1 in methanol.

Refinement details

Crystal data, data collection and structure refinement details are summarized in Table 2 ▶. Atoms S2 and S2′ of one DMSO mol­ecule are disordered over two sites with site-occupation factors of 0.937 (3) and 0.063 (3), respectively. All H atoms were positioned geometrically and refined using a riding model, with C—H = 0.95 Å for Csp 2—H, 0.88 Å for amine N—H and 0.99 Å for methyl­ene C—H. For all H atoms, U iso(H) = 1.2U eq(C,N).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
