Diaqua-bis{5-carboxy-2-[(1H-1,2,4-triazol-1-yl)-meth-yl]-1H-imidazole-4-carboxyl-ato}-manganese(II).

ABSTRACT: In the title compound, [Mn(C(8)H(6)N(5)O(4))(2)(H(2)O)(2)], the Mn(II) ion is situated on an inversion center and is six-coordinated by two N and two O atoms from two L ligands (HL = 2-[(1H-1,2,4-triazol-1-yl)meth-yl]-1H-imidazole-4,5-dicarboxylic acid) and two water mol-ecules in a distorted octa-hedral geometry. In ligand L, the imidazole and triazole rings form a dihedral angle of 74.25?(8)°. Mol-ecules are assembled into a three-dimensional structure via inter-molecular O-H?O, O-H?N and N-H?N hydrogen-bonds, and ?-? inter-actions with a short distance of 3.665?(2)?Å between the centroids of the imidazole and triazole rings of neighbouring mol-ecules.

Project description:In the title compound, [Zn(C(8)H(6)N(5)O(4))(2)(H(2)O)(2)], the six-coordinate Zn(II) ion, which is located on an inversion center, has a distorted octa-hedral configuration.

The coordination sphere is completed by two water mol-ecules in axial positions. There is an intra-molecular O-H?O hydrogen bond in the ligand. In the crystal, mol-ecules are linked via inter-molecular O-H?O, O-H?N and N-H?N hydrogen bonds, forming a three-dimensional structure.

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.
