Crystal structure of (μ-hydrogen di­sulfato)-μ-oxido-bis­[(4,4′-di-tert-butyl-2,2′-bi­pyridine)­oxidovanadium(IV/V)] aceto­nitrile monosolvate

The dinuclear oxidovanadium(IV/V) complex, [V(2)(HS(2)O(8))O(3)(C(18)H(24)N(2))(2)]·CH(3)CN or [V(2)O(2)(μ-O)(μ-H(SO(4))(2))(4,4′-( t )Bubpy)(2)]·CH(3)CN (4,4′-( t )Bubpy = 4,4′-di-tert-butyl-2,2′-bi­pyridine), has crystallographic C (2) symmetry and exhibits a distorted octa­hedral geometry around the vanadium center, where the two 4,4′-( t )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(4))(2) (3−)]. In the crystal, inter­molecular C—H⋯π and π–π inter­actions between the 4,4′-( t )Bubpy ligands are present, leading to a three-dimensional network.
