A two-dimensional copper(I) coordination polymer based on 1-[2-(cyclo-hexyl-sulfan-yl)eth-yl]pyridin-2(1H)-one.

The reaction of copper(I) iodide with 1-[2-(cyclo-hexyl-sulfan-yl)eth-yl]pyridin-2(1H)-one (L, C13H19NOS) in aceto-nitrile/di-chloro-methane results in a crystalline coordination polymer, namely poly[bis-{μ2-1-[2-(cyclo-hexyl-sulfan-yl)eth-yl]pyridin-2(1H)-one}tetra-μ3-iodido-tetra-copper(I)], [Cu4I4L2] n . The asymmetric unit comprises two ligand mol-ecules, four copper(I) ions and four iodide ions. Inter-estingly, the O atoms are bound to the soft copper(I) ions. The stair-step clusters of Cu and I atoms in the asymmetric unit are linked repeatedly, giving rise to infinite chains along [100]. Neighbouring infinite chains are linked through the L mol-ecules, forming a two-dimensional brick-wall structure. These two-dimensional networks are stacked alternately along [001]. Additionally, there are inter-molecular C-H⋯I hydrogen bonds and C-H⋯π inter-actions between the ligands.

Chemical context

Copper(I) complexes have been studied continuously over several decades because of their potential applications as sensors, catalysts, and gas storage materials (Lin et al., 2016 ▸; Ananthnag et al., 2015 ▸; Pal et al., 2015 ▸). They exhibit a variety of structures, photoluminescence, and other physical properties as a result of the d 10 electron configuration of CuI (Peng et al., 2010 ▸; Ford et al., 1999 ▸; Kobayashi & Kato, 2017 ▸). In addition, the arrangement of donor atoms in the ligands may affect both the structures of the complexes and their physical properties. Copper(I) complexes of flexible ligands with N/S donor atoms have been studied (Jeon et al., 2014 ▸; Cho et al., 2015 ▸). Mechanochromism, vapochromism and solvatochromism of such complexes have also been reported (Kwon et al., 2017 ▸; Kang et al., 2015 ▸; Kim et al., 2013 ▸). Herein we describe the synthesis and crystal structure of a copper(I) complex [Cu4I4 L 2] of L (C13H19NOS) with O/S donor atoms. CuI—O bonds have been reported previously in copper(I) coordination polymers with phosphine ligands (Darensbourg et al., 1998 ▸) but those with an O/S donor ligand set are unique as far as we know.

Structural commentary

The asymmetric unit of the title compound, [Cu4I4 L 2], comprises four copper(I) ions, four μ3-iodide ions, and two L ligands as shown in Fig. 1 ▸. In LA (identified by S1) and LB (identified by S2), the pyridyl and cyclo­hexyl rings are in anti and gauche conformations with torsion angles of −154.7 (6)° [C6—S1—C7—C8] and 62.3 (7)° [C19—S2—C20—C21], respectively. All of the CuI atoms (Cu1–Cu4) have distorted tetra­hedral coordination geometries. The Cu1 and Cu2 atoms are bound by three μ3-iodide anions and one S atom, while Cu3 and Cu4 are coordinated by three μ3-iodide ions and one O atom. The ranges of inter­atomic distances in the title compound are 2.7082 (15)–2.7444 (14) Å, 2.297 (2)–2.314 (2) Å, 2.6210 (12)–2.7230 (12) Å, and 2.071 (6)–2.087 (6) Å for Cu—Cu, Cu—S, Cu—I, and Cu—O, respectively (Table 1 ▸). Inter­estingly, the O atoms bind to the soft copper(I) cations, implying that the carbonyl O atoms conjugated with pyridyl rings are softer than the hard, ether-like O atoms.

Supra­molecular features

The step-like clusters of Cu and I atoms in the asymmetric unit are linked repeatedly, generating infinite chains along [100]. Neighbouring infinite chains are linked by the L mol­ecules, forming a two-dimensional brick-wall structure parallel to (001) as shown in Fig. 2 ▸ (Tzeng & Chang, 2009 ▸). Yellow dashed lines display inter­molecular C8—H8A⋯I4ii, C12—H12⋯I1iii and C21—H21B⋯I3iv [H⋯I = 3.26, 3.30, and 3.08 Å, respectively] hydrogen bonds between ligands. Red dashed lines display inter­molecular C5—H5A⋯Cg1v [H⋯Cg1=3.00 Å] inter­actions between the ligands (Fig. 2 ▸ and Table 2 ▸). The two-dimensional brick-wall networks are stacked in an ⋯ababab⋯ fashion along [001] (Fig. 3 ▸).

Database survey

Syntheses and properties of the copper(I) complexes of N/S mixed donor atom ligands have been reported (Jeon et al., 2014 ▸; Cho et al., 2015 ▸). Copper(I) complexes of N/S mixed-donor atom ligands with cyclo­hexyl group have also been reported (Park et al., 2016 ▸, 2017 ▸). In addition, a database search (CSD Version 5.27, last update February 2017; Groom et al., 2016 ▸) showed the crystal structures of three complexes with infinite stair-step (CuI) cluster units (Jess et al., 2007 ▸; Jess & Näther, 2004 ▸; Graham et al., 2000 ▸).

Synthesis and crystallization

Synthesis of 1-[2-(cyclo­hexyl­sulfan­yl)eth­yl]pyridin-2(1 )-one ( )

Thionyl chloride (2.38 g, 20.0 mmol) was added dropwise to 2-(cyclo­hexyl­thio)­ethanol (3.21 g, 20 mmol) in chloro­form. The mixture was stirred under reflux for 1 h then cooled to 253 K. Chloro­form was removed, yielding crude 2-chloro­ethyl­cyclo­hexyl­sulfide. 2-Hy­droxy­pyridine (1.90 g, 20 mmol) and potassium hydroxide (1.12 g, 20 mmol) were dissolved in 10 ml of tetra­hydro­furan and 5 ml of water, and then the solution was added dropwise to the crude chloride. The solution was refluxed for 24 h and cooled. The crude product was extracted by di­chloro­methane. The di­chloro­methane layer was dried with anhydrous Na2SO4, and evaporated to give a crude oil. Column chromatography (silica gel, MeCOOEt/n–C6H14 = 30/70 (v/v), R f = 0.28) (Park et al., 2016 ▸). 1H NMR (300 MHz, CDCl3): 7.28 (dd, 2H, py), 6.52 (d, H, py), 6.11 (d, H, py), 4.01 (t, 2H, NCH2), 2.85 (t, 2H, CH2S), 2.51 (d, H, SCH), 2.00–1.13 [m, 10H, (CH2)5]; 13C NMR (39.51 MHz, DMSO): 161.33, 140.03, 139.52, 119.40, 104.86, 49.21, 42.48, 33.15 27.71, 25.44, 25.29.

Preparation of [Cu

A di­chloro­methane (5 ml) solution of L (0.006 g, 0.025 mmol) was allowed to mix with an aceto­nitrile (5 ml) solution of CuI (0.010 g, 0.053 mmol). The colourless precipitate was filtered and washed with a diethyl ether/aceto­nitrile (5/1 v/v) solution. Single crystals suitable for X-ray analysis were obtained by slow evaporation of di­chloro­methane from the reaction mixture.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 3 ▸. All H atoms were positioned geometrically and refined using a riding model, with C—H = 0.95 Å and U iso(H) = 1.2U eq(C) for aromatic C—H groups, C—H = 0.99 Å and U iso(H) = 1.2U eq(C) for CH2 groups, and C—H = 1.00 Å and U iso(H) = 1.2U eq(C) for Csp3—H groups.

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