catena-Poly[[tetra-kis-(μ-penta-fluoro-benzoato-κO:O')dimolybdenum(II)]-μ-4,4'-bipyridine-κN:N'].

Abstract

In the title compound, [Mo(2)(C(7)F(5)O(2))(4)(C(10)H(8)N(2))](n), the mol-ecule forms a paddle-wheel-type structure. Each Mo(2) (4+) unit is equatorially coordinated by four pentafluoro-benzoate groups, while the axial positions are occupied by two 4,4'-bipyridine mol-ecules. The Mo-Mo bond length of 2.1227 (4) Å is representative of a dimolybdenum quadruple bond. An infinite linear chain parallel to [110] is formed by the Mo(2) (4+) unit coordinating axially to the two N atoms of the 4,4'-bipyridine ligand [Mo-N = 2.594 (2) Å]. The crystal packing shows mol-ecules linked together into a three-dimensional network via Mo-N coordination inter-actions and weak π-π stacking inter-actions between perfluoro-phenyl rings [centroid-centroid distance = 3.7280 (3) Å and centroid-to-plane distance = 3.6103 (12) Å between two penta-fluoro-phenyl rings].

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.
