Poly[diaqua-bis(?-4-carb-oxy-2-propyl-1H-imidazole-5-carboxyl-ato-?N,O:O)calcium(II)].

ABSTRACT: 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-anti-prismatic environment. The water-coordinated Ca atom is N,O-chelated by the monocarboxyl-ate 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.

Project description:In the title complex, [Pb(C(8)H(9)N(2)O(4))(2)(H(2)O)(2)](n), the eight-coordinate Pb(II) atom lies on a twofold rotation axis and adopts a slightly distorted square-anti-prismatic N(2)O(6) coordination geometry. The ligand donor atoms are the tertiary N atoms of the imidazole rings and the carboxyl-ate O atoms of two chelating 5-carb-oxy-2-propyl-1H-imidazole-4-carboxyl-ate ligands, the carb-oxy O atoms of two additional imidazole ligands and two water O atoms. The carb-oxy O and the N,O-chelate systems also link adjacent Pb(II) atoms, forming a two-dimensional layer structure, with four individual Pb(II) atoms located at the corners of a square. These layers are further inter-connected by an extensive array of O-H⋯O and N-H⋯O hydrogen bonds into a three-dimensional network.
