Tris-(4,4'-di-tert-butyl-2,2'-bi-pyridine)(trans-4-tert-butyl-cyclo-hexa-nolato)-deca-μ-oxido-hepta-oxido-hepta-vanadium aceto-nitrile monosolvate including another unknown solvent mol-ecule.

The title hepta-nuclear alkoxido(oxido)vanadium(V) oxide cluster complex, [V(7)(C(10)H(19)O)O(17)(C(18)H(24)N(2))(3)]·CH(3)CN, was obtained by the reaction of [V(8)O(20)(C(18)H(24)N(2))(4)] with 4-tert-butyl-cyclo-hexa-nol (mixture of cis and trans) in a mixed CHCl(3)/CH(3)CN solvent. The complex has a V(7)O(18)N(6) core with approximately C (s) symmetry, which is composed of two VO(4) tetra-hedra, two VO(6) octa-hedra and three VO(4)N(2) octa-hedra. In the crystal, these complexes are linked together by weak inter-molecular C-H⋯O hydrogen bonds between the 4,4'-di-tert-butyl-2,2'-bi-pyridine ligand and the V(7)O(18)N(6) core, forming a one-dimensional network along the c-axis direction. Besides the complex, the asymmetric unit contains one CH(3)CN solvent mol-ecule. The contribution of other disordered solvent mol-ecules to the scattering was removed using the SQUEEZE option in PLATON [Spek (2015 ▸). Acta Cryst. C71, 9-18]. The unknown solvent mol-ecules are not considered in the chemical formula and other crystal data.
