Abstract
The reactions of the Schiff base E-1-(benzo[d]thiazol-2-yl)-2-(1-(2-methoxyphenyl) ethylidene) hydrazine (HL), with metal transition ions (Mn(II), Co(II), Ni(II), Cu(II) and Zn(II)), afforded one type of complex formulated as [M(HL)(Solv)2Cl]+(Cl-). These compounds have been characterized by elemental analysis, UV-Vis, FTIR, 1H and 13C NMR spectroscopies, molar conductivity and room temperature magnetic measurements. The structure of nickel (II) complex has been determined by X-ray crystallography. The complex crystallizes in the monoclinic system space group P21/n with a = 16.1761 (8) Å, b = 8.3212 (4) Å, c = 18.6013 (9) Å, b = 105.441 (3)°, V= 2413.4 (2) Å3, Z = 4, R1 = 0.043, and wR2 = 0.123, Dcalc = 1.429 Mgm-3, \(\mu\) = 1.14 mm-1. The ligand acts in tridentate fashion in its neutral form. Two coordinated alcohol molecules and one chlore atom complete the coordination sphere. The environment around the Ni (II) center is best described as an octahedral geometry. In the crystal structure of the Schiff base ligand, the existence of a strong intramolecular O-H•••Cl hydrogen bonding are observed.
