Abstract

Samarium (III) tris(dithiophosphates, [SmS2P(OR)2 3.3H2O] (where R = ─CH2CH2CH3 or ─C6H5) and [SmS2PO2G3.3H2O] [where G = ─C(CH3)2CH2CH(CH3)─, ─CH2C(CH3)2CH2-, ─C(CH3)2C(CH3)2-, ─CH2CH2CH(CH3), ─CH2C(C2H5)2CH2-, and ─CH(CH3)CH(CH3)-], were prepared by a reaction of SmCl3.6H2O and ammonium dithiophosphates in distilled water. Adducts of the type [SmS2P(OR)2 3.nL] and [SmS2PO2G3.nL] [where n = 1, L = N2C10H8 and n = 2, L = P(C6H5)3] were prepared by a reaction of samarium (III) tris(dithiophosphates) and nitrogen or phosphorus donor bases in benzene. These newly synthesized compounds have been characterized by elemental analysis, molecular weights measurement, thermogravimetric analysis, UV-visible, IR, and 1H and 31P NMR spectral studies. Coordination numbers of eight and nine are suggested for samarium (III) in these derivatives.
