ABSTRACT: The Co(II) atom in the title compound, [Co(C(8)H(5)O(3))(2)(H(2)O)(4)]·4H(2)O, which exists in an all-trans octa-hedral coordination geometry, lies on a center of inversion. The coordinated and uncoordinated water mol-ecules engage in extensive hydrogen-bonding inter-actions, forming a three-dimensional hydrogen-bonded network.

Bis[tetra-aqua-(1,10-phenanthroline-?N,N')cobalt(II)] hexa-aqua-cobalt(II) bis-[3,5-bis-(carboxyl-atometh-oxy)benzoate] tetra-hydrate.

Project description:The title compound, [Co(C(12)H(8)N(2))(H(2)O)(4)](2)[Co(H(2)O)(6)](C(11)H(7)O(8))(2)·4H(2)O, was obtanied by the reaction of cobalt acetate with 3,5-bis-(carb-oxy-meth-oxy)benzoic acid and 1,10-phenanthroline. The asymmetric unit contains one tetra-aqua-(1,10-phenanthroline)cobalt(II) cation, one half of a hexa-aqua-cobalt(II) cation that is completed by inversion symmetry, one 3,5-bis-(carboxyl-atometh-oxy)benzoate trianion and two lattice water mol-ecules. The two Co(II) atoms each show a slightly distorted octa-hedral coordination (CoO(6) and CoO(4)N(2)). The cations, anions and lattice water mol-ecules are linked by an intricate network of O-H?O hydrogen bonds into a three-dimensional structure.

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.

Tetra-aqua-bis-[4-(pyrazin-2-ylsulfanylmethyl-κN)benzoato]cobalt(II).

Project description:In the title compound, [Co(C(12)H(9)N(2)O(2)S)(2)(H(2)O)(4)], the Co(II) ion, lying on an inversion center, has an octa-hedral coordination involving two N atoms of two 4-(pyrazin-2-ylsulf-anylmeth-yl)benzoate ligands and four water mol-ecules. In the crystal, O-H⋯O hydrogen bonds between the coordinated water mol-ecules and uncoordinated carboxyl-ate O atoms, and weak π-π inter-actions [centroid-centroid distance = 4.105 (2) Å] between the benzene and pyrazine rings lead to a three-dimensional supra-molecular network.

trans-Tetra-aqua-bis-(isonicotinamide-?N)cobalt(II) bis-(3-hy-droxy-benzoate) tetra-hydrate.

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. Four water O atoms in the equatorial plane around the Co(II) ion [Co-O = 2.0593?(16) and 2.1118?(16)?Å] form a slightly distorted square-planar arrangement, and the distorted octahedral geometry is completed by the two N atoms [Co-N = 2.1306?(18)?Å] from two isonicotinamide ligands. 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.

Tetra-kis(μ(2)-2-methyl-3,5-dinitro-benzoato-κO:O)bis-[aqua-copper(II)] tetra-hydrate.

Project description:The title compound, [Cu(2)(C(8)H(5)N(2)O(6))(4)(H(2)O)(2)]·4H(2)O, forms a centrosymmetric paddle-wheel-type dimer with an intra-molecular Cu⋯Cu distance of 2.6540 (4) Å. The Cu(II) atom is in a square-pyramidal coordination environment formed by four O atoms of four carboxyl-ate groups and one water mol-ecule, which is located in the apical position. The carboxyl-ate groups are twisted relative to the benzene rings by 11.09 (16) and 45.55 (19)°. The nitro groups are not coplanar with the parent aromatic rings [dihedral angles = 16.2 (3)-51.45 (14)°]. O-H⋯O hydrogen bonds between the coordinated water mol-ecules and one of the nitro groups, as well as π-π stacking inter-actions [centroid-centroid distance = 3.5764 (12) Å] between the benzene rings, assemble the complex mol-ecules into a one-dimensional polymeric structure which is further extended into a three-dimensional polymeric network via O-H⋯O hydrogen bonds involving the water molecules of crystallization.

Tetra-aqua-bis-[4-(4H-1,2,4-triazol-4-yl)benzoato-?N]manganese(II) deca-hydrate.

Project description:In the title compound, [Mn(C(9)H(6)N(3)O(2))(2)(H(2)O)(4)]·10H(2)O, the Mn(II) ion is coordinated by two N atoms from two 4-(4H-1,2,4-triazol-4-yl)benzoate ligands and four water mol-ecules in a distorted octa-hedral geometry. The Mn(II) ion and two coordinated water mol-ecules lie on a twofold rotation axis. The water mol-ecules are involved in O-H?N and O-H?O hydrogen bonds with the triazole N atoms and carboxyl-ate O atoms, yielding a three-dimensional supra-molecular network. ?-? inter-actions between the benzene rings [centroid-centroid distance = 3.836?(9)?Å] are observed.
