Poly[diaqua-μ₄-oxalato-di-μ₆-phosphato- tetrazinc]

The structure of polymeric metal complex, poly[diaqua-μ₄- oxalato-di-μ₆-phosphato-tetrazin c] was studied crystallographically. The compound was prepared under hydrothermal conditions. The structure of the complex had crystallographically independent zinc sites within a zinc phosphate layer. The oxalate ion worked as a spacer between adjacent two-dimensional zinc phosphate layers, thus linking the latter into a three-dimensional architecture. The results show a hydrogen bonding between the water molecules and the framework O atoms.
