Poly[diaqua­bis(μ-4-carb­oxy-2-propyl-1H-imidazole-5-carboxyl­ato-κ3 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-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… CONTINUE READING
