Bis[?-4-(4-carb-oxy-phen-oxy)phthalato]bis-[triaqua-cobalt(II)].

ABSTRACT: The dinuclear title complex, [Co(2)(C(15)H(8)O(7))(2)(H(2)O)(6)], lies across an inversion center. The unique Co(II) ion is coordinated in a slightly distorted octa-hedral coordination geometry by two O atoms from a chelating 4-(carb-oxy-phen-oxy)phthalate ligand, three water O atoms and a further O atom from a bridging carboxyl-ate group of a symmetry-related 4-(carb-oxy-phen-oxy)phthalate ligand. In the crystal, O-H?O hydrogen bonds link the mol-ecules into a three-dimensional network.

catena-Poly[[[triaqua-[3-(4-carb-oxy-phen-oxy)phthalato-?O(2)]manganese(II)]-?-4,4'-bipyridine-?(2)N:N'] 4,4'-bipyridine monosolvate dihydrate].

Project description:In the title compound, {[Mn(C(15)H(8)O(7))(C(10)H(8)N(2))(H(2)O)(3)]·C(10)H(8)N(2)·2H(2)O}(n), the bridging mode of the coordinating 4,4'-bipyridine ligands leads to the formation of polymeric zigzag chains parallel to [0-11]. The chains are separated by 4,4'-bipyridine and water solvent mol-ecules. Within a chain, the Mn(II) atom is six-coordinated by two N atoms of the bridging 4,4'-bipyridine ligands, three water O atoms and one carboxyl-ate O atom of a single deprotonated 3-(4-carb-oxy-phen-oxy)phthalic acid ligand. Both coordinating and solvent 4,4'-bipyridine mol-ecules are situated on centres of inversion. An intricate network of O-H?O and O-H?N hydrogen bonds involving the carb-oxy group, the coordinating water mol-ecules and the two types of solvent mol-ecules leads to the formation of a three-dimensional network.

Project description:The title binuclear complex, [Co(2)(C(8)H(3)NO(6))(2)(C(10)H(8)N(2))(3)(H(2)O)(6)], has been synthesized hydro-thermally from 3-nitro-phthalic acid (H(2)NPA), Co(NO(3))(2)·6H(2)O and 4,4'-bipyridine (4,4'-bipy). The mol-ecule of the complex occupies a special position on an inversion centre. The Co(II) atom has a slightly distorted octa-hedral environment formed by two N atoms from two 4,4'-bipy ligands, one carboxyl-ate O atom from NPA, and three O atoms of water mol-ecules. An extensive O-H?O and N-H?O hydrogen-bonding system links mol-ecules of the complex into a three-dimensional network.

One imidazole ligand is equally disordered over two sites about a twofold rotation axis, while the coordinated N atom of the imidazole is located on the twofold rotation axis. One water O atom has site symmetry 2.

trans-Bis[4-amino-3,5-bis-(2-pyrid-yl)-4H-1,2,4-triazole-?N]diaqua-cobalt(II) bis-(3-carb-oxy-5-nitro-benzoate).

Project description:The title complex, [Co(C(12)H(10)N(6))(2)(H(2)O)(2)](C(8)H(4)NO(6))(2), is composed of a mononuclear cobalt(II) cation and two 3-carb-oxy-5-nitro-benzoate anions for charge balance. In the cation, the Co(II) atom is six-coordinated in a distorted octa-hedral geometry. It bonds to two O atoms of two water mol-ecules, and two pairs of N atoms from two 4-amino-3,5-bis-(2-pyrid-yl)-4H-1,2,4-triazole mol-ecules, which behave as bidentate chelating ligands. There are intra-molecular N-H?N hydrogen bonds in the cation. In the crystal, there are a number of inter-molecular N-H?O and O-H?O hydrogen bonds, as well as inter-molecular ?-? stacking inter-actions [centroid-centroid distances = 3.657?(2) and 3.847?(2)?Å], that link the mol-ecules into two-dimensional networks lying parallel to the ab plane. The presence of C-H?O inter-actions leads to the formation of a three-dimensional network.
