Abstract

In the title complex, [Ca(C8H9N2O4)2(H2O)2]n, the CaII atom is eight-coordinated in a distorted square-antiprismatic environment. The water-coordinated Ca atom is N,O-chelated by the monocarboxylate anion; the carboxyl –CO2 portion engaged in chelation bears an acid hydrogen. The free –CO2 portion engages in bonding to adjacent Ca atoms. The CaII centres are connected through the ligand, forming a layer structure; the layers are linked by hydrogen bonds into a three-dimensional network.
