Poly[[diaquahemi-μ4-oxalato-μ2-oxalato- praseodymium(III)] monohydrate]

Abstract

In the title complex, {[Pr(C2O4)1.5 (H2O) 2]·H2O}n, the Pr III ion, which lies on a crystallographic inversion centre, is coordinated by seven O atoms from four oxalate ligands and two O atoms from two water ligands; further Pr - O coordination from tetra-dentate oxalate ligands forms a three-dimensional structure. The compound crystallized as a monohydrate, the water mol-ecule occupying space in small voids and being secured by O - H⋯O hydrogen bonding as an acceptor from ligand water H atoms and as a donor to oxalate O-acceptor sites. © Yang et al. 2009.
