    Bis(4-methoxybenzoato)-?2O,O?;?O-bis(nicotinamide-?N1)zinc(II)
    (Wiley-Blackwell, 2010) Hoekelek, Tuncer; Saka, Guener; Tercan, Baris; Tenlik, Erdinc; Necefoglu, Hacali
    The asymmetric unit of the title complex, [Zn(C8H7O3)(2)-(C6H6N2O)(2)], contains three crystallographically independent molecules with similar configurations. The Zn-II cation is coordinated by two N atoms of two nicotinamide ligands and three O atoms from two 4-methoxybenzoate anions in a distorted trigonal-bipyramidal geometry. In each independent molecule, one Zn-O bond distance [2.5181 (12), 2.5931 (12) and 2.4085 (12) angstrom for the three molecules] is significantly longer than the other two. In the crystal structure, extensive N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonding links the molecules into a three-dimensional network. pi-pi contacts between the pyridine rings and between the pyridine and benzene rings [centroid-centroid distances = 3.7655 (9) and 3.8453 (10) angstrom, respectively] further stabilize the crystal structure.

    Diaquabis(4-methoxybenzoato-?O 1)bis(nicotinamide-?N 1)cobalt(II) dihydrate
    (Int Union Crystallography, 2010) Hokelek, Tuncer; Dal, Hakan; Tercan, Baris; Tenlik, Erdinc; Necefoglu, Hacali
    In the mononuclear title compound, [Co(C8H7O3)(2)(C6H6N2O)(2)(H2O)(2)]center dot 2H(2)O, the CoII ion is located on a crystallographic inversion center. The asymmetric unit is completed by one 4-methoxybenzoate anion, one nicotinamide (NA) ligand and one coordinated and one uncoordinated water molecule. All ligands act in a monodentate mode. The four O atoms in the equatorial plane around the CoII ion form a slightly distorted square-planar arrangement, while the slightly distorted octahedral coordination is completed by the two pyridine N atoms of the NA ligands in the axial positions. The dihedral angle between the carboxylate group and the attached benzene ring is 6.47 (7)degrees, while the pyridine and benzene rings are oriented at a dihedral angle of 72.80 (4)degrees. An O-H...O hydrogen bond links the uncoordinated water molecule to one of the carboxylate groups. In the crystal structure, intermolecular O-H...O, N-H...O and C-H...O hydrogen bonds link the molecules into a three-dimensional network.

    In the mononuclear title compound, [Ni(C8H7O3)(2)(C6H6N2O)(2)(H2O)(2)]center dot 2H(2)O, the NiII ion is located on a crystallographic inversion center. The asymmetric unit further contains one 4-methoxybenzoate anion, one nicotinamide (NA) ligand and one coordinated and one uncoordinated water molecule; all ligands are monodentate. The four O atoms in the equatorial plane around the NiII ion form a slightly distorted square-planar arrangement, while the slightly distorted octahedral coordination is completed by the two pyridine N atoms of the NA ligands in the axial positions. The dihedral angle between the carboxylate group and the attached benzene ring is 7.2 (1)degrees, while the pyridine and benzene rings are oriented at a dihedral angle of 72.80 (4)degrees. An intramolecular O-H...O hydrogen bond links the uncoordinated water molecule to one of the carboxylate groups. In the crystal structure, intermolecular O-H...O, N-H...O and C-H...O hydrogen bonds link the molecules into a three-dimensional network.
