Crystal structure of (μ-hydrogen di-sulfato)-μ-oxido-bis-[(4,4'-di--butyl-2,2'-bi-pyridine)-oxidovanadium(IV/V)] aceto-nitrile monosolvate.

The dinuclear oxidovanadium(IV/V) complex, [V(HSO)O(CHN)]·CHCN or [VO(μ-O)(μ-H(SO))(4,4'-Bubpy)]·CHCN (4,4'-Bubpy = 4,4'-di--butyl-2,2'-bi-pyridine), has crystallographic symmetry and exhibits a distorted octa-hedral geometry around the vanadium center, where the two 4,4'-Bubpy ligands are nearly orthogonal to each other. The two vanadium ions are linked by an oxo anion and a unique protonated sulfate anion [H(SO) ]. In the crystal, inter-molecular C-H⋯π and π-π inter-actions between the 4,4'-Bubpy ligands are present, leading to a three-dimensional network.
