摘要：

The sodium salts of lanthanide nitrilotris(mehylenephosphonate) complexes [Na(H2O)(x)](2)[Ln(III)Na(6)H(H2O)(10){N(CH2PO3)(3)}(2)] nH(2)O, where Ln(III) = Pr (I), and Nd (II), were prepared, isolated, and studied. The isostructural crystals are monoclinic, space group P2(1)/c, Z = 2; for complex I, a = 11.8168(7), b= 10.5403(9), c = 19.8094(10) angstrom, = 94.232(5)degrees; for complex II, a = 11.7999(2), b = 10.5495(2), c = 19.7976(3)angstrom, = 94.158(2)degrees. The lanthanide ions are coordinated at the center of a cage consisting of two {N(CH2PO3)(3)} acid residues and six sodium ions, which form P-O-Na-O-P bridges. The Ln coordination polyhedron is a regular rhombohedron (CIF files CCDC nos.1825702 (I), 1825700 (II)).
