Tetra­kis(μ-penta­fluoro­benzoato-κ(2) O:O′)bis­[(tetra­hydro­furan-κO)molybdenum(II)]

In the asymmetric unit of the title compound, [Mo(2)(C(7)F(5)O(2))(4)(C(4)H(8)O)(2)], two independent half-mol­ecules are present, which are completed by a crystallographically imposed center of inversion between the individual Mo atoms. In each mol­ecule, four penta­fluoro­benzoate anions bridge th...

Sumario:In the asymmetric unit of the title compound, [Mo(2)(C(7)F(5)O(2))(4)(C(4)H(8)O)(2)], two independent half-mol­ecules are present, which are completed by a crystallographically imposed center of inversion between the individual Mo atoms. In each mol­ecule, four penta­fluoro­benzoate anions bridge the quadruply bonded Mo(2) (4+) unit that is, in addition, axially coordinated by two O atoms of tetra­hydro­furan (THF) mol­ecules. In the two independent mol­ecules, the mean Mo—Mo bond length is 2.110 Å. Since the THF mol­ecules are equally disordered over two sets of sites, there are four different Mo—O distances in both half-mol­ecules with an overall mean of 2.542 Å. A zigzag chain is formed by π–π stacking inter­actions between penta­fluoro­phenyl rings, indicated by a centroid–centroid distance of 3.7054 (11) Å and a centroid-to-plane distance of 3.4169 (3) Å. The extension of the unit gives a three-dimensional network structure with the THF mol­ecules located in the voids.
