The title compound, [Ni(C23H17N4O)(N3)], was obtained by the reaction of the Schiff base ligand 2-[(tri-2-pyridylmethyl)iminomethyl]phenol with sodium azide and nickel(II) perchlorate in methanol solution. The NiII atom is four-coordinated by the phenolate O, the imine N and a pyridine N atom of the Schiff base ligand, and by the terminal N atom of an azide ligand, forming a square-planar geometry. The other two pyridyl rings are oriented at an angle of 72.29 (11)° to each other.

The title compounds, [Cu(C16H23N2O)SCN] (1) and [Cu(C16H23N2O)N3] (2), containing a tridentate Schiff base ligand, which is the 1:1 condensation product of benzoylacetone and 2- diethylaminoethylamine, have been synthesised and their crystal structures determined. The structure of 1 is based on a four coordinate copper centre with square-planar geometry formed by the N2O donor set of the Schiff base and an N atom of the thiocyanate anion. A similar arrangement occurs in 2 with the N2O donor set of the Schiff base and an N atom of the azide anion. The Cu-N and Cu-O distances are 1.924(8), 2.073(8), 1.927(9) and 1.910(6)Å , for 1 and 1.960(4), 2.050(4), 1.935(4) and 1.907(3) for 2, respectively.

Thiosemicarbazone Complexes

Three nickel thiosemicarbazone mixed ligands complexes have been synthesized. Complexes with the formula [NiL(PPh3)]Cl, [Ni2L2(Phen)],[Ni2L2(Bpy)] (where L= 2,3,4-trihydroxybenzaldehydethiosemicarbazone, PPh3=Triphenylphosphine, Phen=1,10-phenanthroline, Bpy= 2,2 –Bipyridine)have been characterized by IR spectroscopy, as well as elemental analysis. The structure of [NiL (PPh3)]Cl has been determined by X-raycrystallography. The crystal structure of this complex shows that the Schiff base ligand functions as an N,O,S chelating anion to the phosphine –coordinated nickel(II) atom, which exists as a distorted square – planar geometry.

In the title compound, [Cu(C19H16Br4N2O2)], the CuIIion and the substituted C atom of the diamine fragment lie on a crystallographic twofold rotation axis. The geometry around the CuIIion is distorted square-planar, which is defined by the N2O2donor atoms of the coordinated Schiff base ligand. The dihedral angle between the symmetry-related substituted benzene rings is 25.33 (14)°. The crystal structure is stabilized by an intermolecular π–π interaction [centroid–centroid distance = 3.8891 (18) Å].
