Abstract

A new series of gadolinium complexes with mixed ligands, dialkyl dithiocarbamate and 1,10-Phenantroline were successfully synthesized using "in situ" methods. Microelemental analysis data of complexes are in agreement with the general formula Gd[S2 CNR'R"]3Phen (R'=ethyl, methyl; R" = butyl, heptyl, isopropyl, isobutyl, benzyl and cyclohexyl; Phen = 1,10-phenantroline). These complexes have been characterized using elemental analysis, infrared, thermogravimetric analysis, conductivity and magnetic measurements. Infrared spectra of complexes showed the thioureide v(C-N) bands were in the region of 1450-1490 cm-1. The single v(C-S) bands appeared in the region of 959-1003 cm-1 and v(C-H) bands in the region of 2853-2931 cm-1. The crystal structure of tris(N,N-methylbenzyldithiocarbamate) (1,10-phenantroline) gadolinium(III) adopts a triclinic system (space group P?) with a distorted dodecahedron geometry with a = 11.04(6) Å, b = 12.65(7) Å, c = 17.13(10) Å, c = 73.86°(8) β = 74.54°(8) γ = 72.34°(8) and Z = 2. Three dithiocarbamates and one phenanthroline ligands were coordinated to the central Gd atom in bidentate manner.
