The central Ni(II) atom in the title complex, [Ni(C(16)H(13)BrN(2)O(2))(C(5)H(5)N)], is in a square-planar trans-N(2)O(2) environment defined by the NO(2) donor atoms of the tridentate hydrazone ligand and the monodentate pyridine ligand. The pyridine mol-ecule forms a dihedral angle of 9.99 (11)° with the least-squares plane through the NiN(2)O(2) atoms.

The crystal structure of the title complex, [Cu(2)(C(15)H(10)Cl(2)N(2)O(2))(2)(C(5)H(5)N)(2)], features centrosymmetric dimers. The Cu(II) ion is penta-coordinated in a quadratic pyramidal mode. The quadratic plane is formed by the O,O',N-tridentate ligand and a pyridine mol-ecule. The fifth coordination site is occupied by the O atom of another ligand showing a significantly longer Cu-O bond.

In the title compound, [Cu(C(11)H(11)NO(3))(C(11)H(16)N(4))]·H(2)O, the Cu(II) atom is five-coordinate in a distorted square-pyramidal geometry. The basal positions are occupied by three donor atoms from the tridentate Schiff base ligand and by one N atom from a bis-(3,5-dimethyl-prazol-l-yl)methane ligand. The apical position is occupied by the N atom of the other ligand of this type. There ar...
