Bis[μ-5-(5-carboxylato-3-pyridyl)tetrazolato-κ3N1,N5:N2]bis[triaquazinc(II)]

Abstract

In the title complex, [Zn2(C7H3N5O2)2(H2O)6], the 5-(5-carboxylato-3-pyridyl)tetrazolate ligand chelates the ZnII center through one pyridyl N and one tetrazolate N atom, and uses another N atom to bridge to the second Zn atom, forming a centrosymmetric dinuclear unit. Three coordinated water molecules complete the distorted octahedral geometry of the ZnII atom. O—H...O and O—H...N hydrogen bonds involving the coordinated water molecules, tetrazolate N atoms and the carboxylate group result in a three-dimensional structure.
