Abstract

The new tetradentate symmetrical (2R, 2'S)1,1'-piperazine-1,4-diyldipropane-2-thiol) (L-1), (2S)-1-[bis (2-aminoethyl) amino] propan-2-ol) (L-2), and 2-{(E)-[((1R, 2S)-2-{[(1Z)-(2-hydroxy phenyl)methylene]amino}cyclohexyl) imino] methyl} phenol (L-3) ligands were synthesized and characterized on the basis of FT-IR, H-1, C-13 NMR, EI mass, and elemental analysis. Three commercially available ligands, (2,2'-[ethane-1,2-diylbis(thio)] diethanol (L-4), 2,2'-dithiodiethanenamine (L-5), and (2,2-[ethane-1,2-diyldi(imino)] diethanol (L-6), were also studied. Pt(II) complexes were characterized by FTIR, elemental analysis and thermal methods. Thermal behaviors of these complexes were investigated in the range 10-1000 degrees C. Magnetic properties were also studied, and the all complexes were found to be diamagnetic. The structures consist of the monomeric units in which the Pt(II) atoms exhibit square planar geometry. N,N'-bis(salicylidene)-1,2-cyclohexane has been synthesized and characterized by X-ray single crystal diffraction measurement. The ligand crystallizes in monoclinic crystal system and space group, Cc.
