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, [V2(HS2O8)O3(C18H24N2)2] · CH3CN or [V2O2( μ -O)( μ -H(SO4)2)(4,4 ′ -tBubpy)2] · CH3CN (4,4 ′ -tBubpy = 4,4 ′ -di-tert-butyl-2,2 ′ -bipyridine), has crystallographic C2 symmetry and exhibits a distorted octahedral geometry around the vanadium center, where the two 4,4 ′ -tBubpy 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)23 − ]. In the crystal, intermolecular C — H... π and π – π interactions between the 4,4 ′ -tBubpy ligands are present, leading to a three-dimensional network.
