Poly[diaqua­bis(μ-4-carb­oxy-2-propyl-1H-imidazole-5-carboxyl­ato-κ(3) N (3),O (4):O (5))calcium(II)]

In the title complex, [Ca(C(8)H(9)N(2)O(4))(2)(H(2)O)(2)](n), the Ca(II) 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 –CO(2) portion engaged in chelation bears an acid hydrogen. T...

Descripción
Sumario:In the title complex, [Ca(C(8)H(9)N(2)O(4))(2)(H(2)O)(2)](n), the Ca(II) 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 –CO(2) portion engaged in chelation bears an acid hydrogen. The free –CO(2) portion engages in bonding to adjacent Ca atoms. The Ca(II) centres are connected through the ligand, forming a layer structure; the layers are linked by hydrogen bonds into a three-dimensional network.
