Diaqua-[5,5'-dicarb-oxy-2,2'-(ethane-1,2-di-yl)bis-(1H-imidazole-4-carboxyl-ato)]cobalt(II).

ABSTRACT: In the title complex, [Co(C(12)H(8)N(4)O(8))(H(2)O)(2)], the Co(II) atom is coordinated by two N and two O atoms of the tetra-dentate 5,5'-dicarb-oxy-2,2'-(ethane-1,2-di-yl)bis-(1H-imidazole-4-carboxy-l-ate) anion. The slightly distorted octa-hedral coordination environment is completed by the O atoms of two water mol-ecules in axial positions. An intra-molecular O-H?O hydrogen bond between the carb-oxy and carboxyl-ate groups stabilizes the mol-ecular configuration. Adjacent mol-ecules are linked through O-H?O and N-H?O hydrogen bonds between the carb-oxy/carboxyl-ate groups, water mol-ecules and imidazole fragments into a three-dimensional network.

Project description:In the title compound, [Co(C(4)H(3)N(2)O(2))(2)(H(2)O)(2)], the Co(II) ion is located on a twofold rotation axis and shows a distorted octa-hedral coordination configuration, defined by two N,O-bidentate 1H-imidazole-4-carboxyl-ate ligands in the equatorial plane and two water mol-ecules in the axial positions.

{3,3',5,5'-Tetra-meth-oxy-2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenol-ato}-copper(II).

Project description:In the title square-planar copper complex, [Cu(C(20)H(22)N(2)O(6))], the Cu-N and Cu-O bond lengths are significantly longer than those of its isostructural nickel analog. The title structure is related to that of the corresponding monohydrate. There are significant differences in the conformations of the two complexes. While the monohydrate is mainly planar, in the title compound there is a slight twist in the two benzene rings at each end of the complex [dihedral angle = 13.14?(6)°]. All the atoms of the meth-oxy substitutents are in the plane of the ring to which they are attached (r.m.s. deviation = 0.0079?Å) except for one of the meth-oxy C atoms, which deviates slightly [0.309?(4)?Å]. In the crystal, weak C-H?O inter-molecular inter-actions link the mol-ecules.

Poly[diaqua-(?(5)-1H-imidazole-4,5-di-carboxyl-ato)(?(4)-1H-imidazole-4,5-di-carboxyl-ato)tris-ilver(I)ytterbium(III)].

Project description:The asymmetric unit of the title compound, [Ag(3)Yb(C(5)HN(2)O(4))(2)(H(2)O)(2)](n), contains three Ag(I) ions, one Yb(III) ion, two imidazole-4,5-dicarboxyl-ate ligands and two coordinating water mol-ecules. The Yb(III) atom is eight-coordinated, in a bicapped trigonal prismatic coordination geometry, by six O atoms from three imidazole-4,5-dicarboxyl-ate ligands and two coordinating water mol-ecules. The two-coordinated Ag(I) ions exhibit three types of coordination environments. One Ag(I) atom is bonded to two N atoms from two different imidazole-4,5-dicarboxyl-ate ligands. The other two Ag(I) atoms are each coordinated by one O atom and one N atom from two different imidazole-4,5-dicarboxyl-ate ligands. These metal coordination units are connected by bridging imidazole-4,5-dicarboxyl-ate ligands, generating a two-dimensional heterometallic layer. These layers are stacked along the a axis via O-H?O hydrogen-bonding inter-actions to generate a three-dimensional framework.
