Piperazinium aquabis(oxalato)oxidovanadate(IV) dihydrate

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) Å and V—O = 1.9932 (12)–2.2176 (12) Å]]. 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.

“…Many vanadium complexes of the oxalate dianion have been reported having biological (Kordowiak et al, 2000;Leó n et al, 2013) and catalysis applications (Mishra et al, 2002;Maurya et al, 2003). Many non-polymeric structural architectures of vanadium oxalate compounds have been reported, among which the synthesis of mononuclear bis(oxalato)dioxovanadate(V) complexes is limited to the easy formation of aquabis-(oxalato)oxidovanadate(IV) (Lin et al, 2004, Aghabozorg et al, 2007, Sehimi et al, 2016. Dioxovanadate(V) compounds have been studied less often; reported structures include triammonium bis(oxalato)dioxovanadate(V) dihydrate, (NH 4 )[VO 2 (C 2 O 4 ) 2 ]Á2H 2 O (Hoard et al, 1971;Atovmyan et al, 1972) and tripotassium bis(oxalato)dioxovanadate(V) trihydrate, K 3 [VO 2 (C 2 O 4 )]Á3H 2 O (Drew et al, 1974;Stomberg, 1986).…”

“…In addition to that, the use of pyridine and its derivatives in those hybrid materials may also provide biological activity as reported by Markees et al (1968). Many compounds containing the vanadyl V O group combined with oxalate ligands have been isolated as mononuclear (Lin et al, 2004;Aghabozorg et al, 2007;Oughtred et al, 1976) or dinuclear (Zheng et al, 1998) compounds.…”
