چکیده
In the title compound, [Ni(2)(CO(3))(C(5)H(6)N(2))(8)(H(2)O)]Cl(2)·5H(2)O, one of the the Ni(II) ions is six-coordinated in a distorted octa-hedral geometry, with the equatorial plane defined by four pyridine N atoms from four amino-pyridine ligands, the axial positions being occupied by one water O and a carbonate O atom. The other Ni(II) ion is also six-coordinated, by four other pyridine N atoms from four other amino-pyridine ligands and two carbonate O atoms to complete a distorted octa-hedral geometry. In the crystal structure, mol-ecules are linked into an infinite three-dimensional network by O-H⋯O, N-H⋯Cl, N-H⋯O, O-H⋯N, C-H⋯O, C-H⋯N and C/N-H⋯π inter-actions involving the pyridine rings.

The two Ni(II) atoms in the title complex, [Ni(2)(CN)(4)(C(16)H(36)N(4))]·C(3)H(7)NO·0.5H(2)O, are bridged by a cyanide ion. The macrocycle folds around one Ni(II) atom, which is five-coordinated in an NiN(5) square-pyramidal geometry. The other Ni(II) atom is surrounded by the cyanide ions in an NiN(4) square-planar geometry. The dimethyl-formamide solvent mol-ecule is disordered over two posi...

The title compound, (CH(6)N(3))[Zn(2)(C(7)H(3)NO(5))(2)(C(7)H(4)NO(5))(H(2)O)]·2H(2)O, has an anionic binuclear complex of Zn(II) balanced with a guanidinium cation. There are two uncoord-inated water mol-ecules in the structure. The asymmetric unit of the compound has two different coordination types (the coordination of Zn1 is distorted trigonal-bipyramidal, while that of Zn2 is distorted oct...

The title complex, [Cu(2)(C(15)H(12)N(3)O(2)S)(2)(NO(3))(CH(3)OH)]NO(3), has two Cu(II) centres coordinated by two deprotonated 2-[(benzothia-zol-2-yl)hydrazonometh-yl]-6-methoxy-phenol ligands, a methanol mol-ecule and a nitrate ion. Both Cu(II) centres are penta-coordinated in a distorted square-pyramidal fashion. The crystal structure is stabilized by N-H⋯O and O-H⋯O hydrogen bonds.

Two distinct coordination geometries are found in the binuclear title complex, [Ni(2)(C(13)H(19)N(2)O(2))(2)(N(3))(2)(CH(3)OH)], as one Schiff base ligand is penta-dentate, coordinating via the anti-cipated oxide O, imine N and amine N atoms (as for the second, tridentate, ligand) but the oxide O is bridging and coordination also occurs through the meth-oxy O atom. The Ni(II) atoms are linked b...
