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. |
