Hexaaqua-cobalt(II) bis-(5-acetyl-2-hy-droxy-benzoate) dihydrate.

ABSTRACT: In the title compound, [Co(H(2)O)(6)](C(9)H(7)O(4))(2)·2H(2)O, the Co(2+) cation lies on a twofold rotation axis and is coordinated by six water mol-ecules in a distorted octa-hedral geometry. In the 5-acetyl-2-hy-droxy-benzoate anion, the hy-droxy group links with the carboxyl-ate group via an intra-molecular O-H?O hydrogen bond and the acetyl group is twisted to the benzene ring at a dihedral angle of 16.99?(12)°. In the crystal structure, the cations, anions and water mol-ecules are linked by extensive O-H?O hydrogen bonding.

Project description:In the crystal structure of the title compound, [Mg(H(2)O)(6)](C(7)H(5)O(6)S)(2)·2H(2)O, the octa-hedral complex cation lies on an inversion centre and is hydrogen bonded through the coordinated water molecules to the substituted benzene-sulfonate monoanions and the water mol-ecules of solvation. These inter-actions together with a carb-oxy-lic acid O-H⋯O(sulfonate) association give a three-dimensional structure.

Project description:The asymmetric unit of the title compound, [Co(C(6)H(6)N(2)O)(2)(H(2)O)(4)](C(7)H(5)O(3))(2)·4H(2)O, contains one-half of the complex cation with the Co(II) ion located on an inversion center, a 3-hy-droxy-benzoate counter-anion and two uncoordinated water mol-ecules.

In the anion, the carboxyl-ate group is twisted from the attached benzene ring at 8.84?(17)°. In the crystal, a three-dimensional hydrogen-bonding network, formed by classical O-H?O and N-H?O hydrogen bonds, consolidates the crystal packing, which exhibits ?-? inter-actions between the benzene and pyridine rings, with centroid-centroid distances of 3.458?(1) and 3.606?(1)?Å, respectively.

Project description:In the title hydrated mol-ecular salt, [Mg(H(2)O)(6)](C(13)H(9)BrNO(4)S)(2)·2H(2)O, the Mg(2+) ion (site symmetry ) adopts a near regular MgO(6) octa-hedral coordination geometry. In the anion, the dihedral angle between the aromatic rings is 2.5 (2)° and an intra-molecular O-H⋯N hydrogen bond generates an S(6) ring.

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.
