Some highly stable V(III) complexes involving the biologically important and chemically interesting ONO donor ligand pyridine-2,6-dicarboxylic acid (dipicolinic acid, DPAH2) are reported. They include both homo- and hetero-chelates involving DPAH2 and some other bidentate chelating ligands and one of them is a new highly stable seven- coordinated mononuclear V(III) complex, [V(DPA)(PA)(H2O)2]·H2O 4 (PA 4;= 4;picolinate anion). The complex 4 containing two different α-N-heterocyclic carboxylates has a pentagonal bipyramidal structure with the equatorial plane accommodating the ONO and NO donor points while the two water molecules occupy the axial positions. |
