Lanthanum(III) tris(dithiophosphates), [La{S2P(OR)2}3] (where R=-CH2CH2CH3 or -C6H5) and [La{S2PO2G}3] [where G=-C(CH3)2CH2CH(CH3)-, -CH2C(CH3)2CH2-, -C(CH3)2C(CH3)2- and -CH2CH2CH(CH3)-] were prepared in methanolic solutions of anhydrous LaCl3 and ammonium dithiophosphates. Addition complexes of the type [La{S2P(OR)2}3·nL] and [La{S2PO2G}3·nL] [where n = 1, L = N2C10H8 or N2C12H8 and n = 2, L = P(C6H5)3] were prepared by reaction of lanthanum(III) tris(dithiophosphates) and nitrogen or phosphorus donor bases in benzene. These newly synthesized derivatives have been characterized by elemental analyses, molecular weights, IR, 1H and 31P NMR spectral measurements. Coordination numbers of six and eight are suggested for lanthanum(III) in these derivatives. |
