Catena-Poly[N-methylpiperazinium(2+) [[bis(oxalato-κ2O,O′)zirconate(IV)]-μ2-oxalato-κ4O,O′:O′′,O′′′

Abstract

The Zr atom in the title compound, {(C5H11N2)[Zr(C2O4)3]}n, is chelated by four oxalate groups in a square-antiprismatic geometry. Bridging by one of the three oxalate groups in the asymmetric unit gives rises to a helical tris­(oxalato)­zirconate chain that propagates along the b axis of the unit cell. The dications surround the chains and are tightly hydrogen bonded to them, resulting in a three-dimensional network.
