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

Abstract

The dinuclear oxidovanadium(IV/V) complex, [V2(HS2O8)O3(C18H24N2)2]·CH3CN or [V2O2(μ-O)(μ-H(SO4)2)(4,4′- t Bubpy)2]·CH3CN (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(SO4)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.
