Poly[[tetra-aqua-bis(1H-imidazole-κN)bis-[2-(oxaloamino)benzoato(3-)]dicopper(II)barium(II)] dihydrate].

ABSTRACT: In the title coordination polymer, {[BaCu(2)(C(9)H(4)NO(5))(2)(C(3)H(4)N(2))(2)(H(2)O)(4)]·2H(2)O}(n), the Ba(2+) cation is deca-coordinate, ligated by four aqua ligands and four [Cu(C(9)H(4)O(5)N)(C(3)H(4)N(2))] 'complex ligands'. The Cu(II)-containing complex-ligands are bridged by the Ba(2+) cations, resulting in a one-dimensional polymeric chain structure. The crystal structure is maintained via N-H⋯O and O-H⋯O hydrogen bonds. There is one disordered solvent water mol-ecule in the asymmetric unit, with occupancies of 0.44 (2) and 0.56 (2).

Project description:In the title compound, [Cu(C(9)H(6)N(3)O(2))(2)(H(2)O)(4)]·2H(2)O, the Cu(II) atom lies on an inversion center and is six-coordinated by two N atoms from two 4-(1,2,4-triazol-4-yl)benzoate ligands and four water mol-ecules in a distorted octa-hedral geometry. In the crystal, inter-molecular O-H⋯O hydrogen bonds lead to a three-dimensional supra-molecular network. Intra-molecular O-H⋯N hydrogen bonds and π-π inter-actions between the benzene rings and between the benzene and triazole rings [centroid-centroid distances = 3.657 (1) and 3.752 (1) Å] are observed.

Aqua-bis(1H-imidazole-κN)bis-(4-methyl-benzoato-κO,O')cadmium(II).

Project description:In the title compound, [Cd(C(8)H(7)O(2))(2)(C(3)H(4)N(2))(2)(H(2)O)], the Cd(II) atom is coordinated by four carboxyl-ate O atoms from two bidentate chelating 4-methyl-benzoate ligands, two N atoms from two imidazole ligands and one water mol-ecule in a distorted penta-gonal bipyramidal geometry. Inter-molecular O-H⋯O hydrogen bonds between the coordinated water mol-ecule and the carboxyl-ate O atoms of 4-methyl-benzoate lead to an infinite chain. These chains are further self-assembled into a two-dimensional layer through N-H⋯O hydrogen bonds between the imidazole ligands and carboxyl-ate groups. One of the imidazole ligands is disordered over two positions with site-occupancy factors of 0.737 (4) and 0.263 (4).

Tetra-aqua-bis(isonicotinamide-κN)cobalt(II) bis-(4-formyl-benzoate) dihydrate.

Project description:The asymmetric unit of the crystal structure of the title complex, [Co(C(6)H(6)N(2)O)(2)(H(2)O)(4)](C(8)H(5)O(3))(2)·2H(2)O, contains one-half of the complex cation with the Co(II) ion located on an inversion center, a 4-formyl-benzoate (FB) counter-anion and an uncoordinated water mol-ecule. The four O atoms in the equatorial plane around the Co(II) ion form a slightly distorted square-planar arrangement with an average Co-O bond length of 2.086 Å; the slightly distorted octa-hedral coordination is completed by the two N atoms of the isonicotinamide (INA) ligands at a slightly longer distance [2.1603 (14) Å] in the axial positions. The dihedral angle between the carboxyl-ate group and the attached benzene ring is 5.93 (13)°, while the pyridine and benzene rings are oriented at a dihedral angle of 3.09 (6)°. In the crystal structure, O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network. π-π Contacts between the benzene and pyridine rings [centroid-centroid distance = 3.758 (1) Å] may further stabilize the crystal structure.

Project description:The asymmetric unit of the title complex, [Ni(C(6)H(6)N(2)O)(2)(H(2)O)(4)](C(8)H(5)O(3))(2)·2H(2)O, contains one-half of the complex cation with the Ni(II) atom located on an inversion center, a 4-formyl-benzoate (FB) counter-anion and an uncoordinated water mol-ecule. The four O atoms in the equatorial plane around the Ni atom form a slightly distorted square-planar arrangement and the slightly distorted octa-hedral coordination is completed by the two N atoms of the isonicotinamide (INA) ligands at a sligthly longer distance in the axial positions. The dihedral angle between the carboxyl-ate group and the attached benzene ring is 8.14 (11)°, while the pyridine and benzene rings are oriented at a dihedral angle of 3.46 (6)°.
