Poly[tetra-deca-aqua-tetra-kis-(μ(3)-imidazole-4,5-dicarboxyl-ato)hexa-μ(3)-sulfato-cobalt(II)hexa-samarium(III)].

ABSTRACT: In the title three-dimensional compound, [CoSm(6)(C(5)H(2)N(2)O(4))(4)(SO(4))(6)(H(2)O)(14)](n), the Co(II) ion is six-coordinated with two O atoms and two N atoms from two imidazole-4,5-dicarboxyl-ate ligands and two coordinated water mol-ecules, giving a slightly distorted octa-hedral geometry. One Sm(III) ion is eight-coordinated in a bicapped trigonal-prismatic coordination geometry by four O atoms from two imidazole-4,5-dicarboxyl-ate ligands, two O atoms from two SO(4) (2-) anions and two coordinated water mol-ecules. The other two Sm(III) ions are nine-coordinated in a tricapped trigonal-prismatic coordination geometry; one of these Sm(III) ions is bonded to four O atoms from two imidazole-4,5-dicarboxyl-ate ligands, three O atoms from three SO(4) (2-) anions and two water O atoms,
