Abstract
The title hepta-nuclear alkoxido(oxido)vanadium(V) oxide cluster complex, [V7(C10H19O)O17(C18H24N2)3]·CH3CN, was obtained by the reaction of [V8O20(C18H24N2)4] with 4-tert-butyl-cyclo-hexa-nol (mixture of cis and trans) in a mixed CHCl3/CH3CN solvent. The complex has a V7O18N6 core with approximately C s symmetry, which is composed of two VO4 tetra-hedra, two VO6 octa-hedra and three VO4N2 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 V7O18N6 core, forming a one-dimensional network along the c-axis direction. Besides the complex, the asymmetric unit contains one CH3CN 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.

Summary
In contrast to anionic vanadium oxide clusters (POVs) (Hayashi, 2011), isolated nonionic vanadium oxide clusters are still limited in number, they have the potential to exhibit chemical properties distinct from those of POVs.
