Online published on 22 February, 2013. Abstract Some new lanthanide (III) complexes, containing Schiff bases, of the type [(Cl)2Ln(L)(H2O)4] and [(Cl)Ln(L)2(H2O)3] [where Ln= Neodymium(III), Gadolinium (III), Samarium (III) & Yttrium (III), L= Schiff base ligand; salicylidene-sulphadiazine (ssdH)] have been synthesized and characterized by elemental (Ln, C, H, N, & Cl) analysis and spectral (IR, 1H-, 13C- NMR and FABMS) data, whereas the structure of the complexes have been tentatively determined by FAB-MS spectral studies. Thermogravimetric Analysis (TGA) was found to be on Perkin elmer diamond TG/DTA and X-ray powder diffraction of the complex was also found to be on Rigaku Model D/Max-2200 PC using CU-Ko1 radiation (11 = 1.5406 A). The crystallite size of the complexes [(Cl2Nd(L)(H2O)4] (1) and [(Cl)2Sm(L)(H2O)4] (5) were found to be 312.28 A and 152.67A respectively. These complexes were found to be coloured solid and were only soluble in polar solvents DMF & DMSO.
