catena-Poly[[tetra­kis­(μ-penta­fluoro­benzoato-κ(2) O:O′)dimolybdenum(II)]-μ-4,4′-bipyridine-κ(2) N:N′]

In the title compound, [Mo(2)(C(7)F(5)O(2))(4)(C(10)H(8)N(2))](n), the mol­ecule forms a paddle-wheel-type structure. Each Mo(2) (4+) unit is equatorially coordinated by four pentafluoro­benzoate groups, while the axial positions are occupied by two 4,4′-bipyridine mol­ecules. 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 mol­ecules linked together into a three-dimensional network via Mo—N coordination inter­actions and weak π–π stacking inter­actions between perfluoro­phenyl rings [centroid–centroid distance = 3.7280 (3) Å and centroid-to-plane distance = 3.6103 (12) Å between two penta­fluoro­phenyl rings].
