Abstract
|
The title compound, (C4H12N2)[V(C2O4)2O(H2O)]2H2O, has been obtained by the reaction of vanadium(III) chloride with piperazinediium oxalate in aqueous solution. It shows distorted octahedral geometry [V O = 1.6010 (12) A ˚ and V—O = 1.9932 (12)–2.2176 (12) A ˚ ]]. The structure exhibits intermolecular N—H O and C—H O hydrogen bonds. The uncoordinated water molecules contribute to the formation of the supramolecular structure via O—H O hydrogen bonds.
