英文摘要	The title complexes: {[Nd2(Cys)2(OH2)8](ClO4)6.3H2O}n (1) and [Nd2(Phe)4(OH2)8](ClO4)6.H2O (2) were prepared in aqueous solutions (where Cys=cystine, Phe=phenylalanine), and their crystal structures were determined by X-ray diffraction methods. For complex 1, the crystal belongs to the orthorhombic space group P2(1)2(1)2(1), with cell parameters: a = 13.674(3) angstrom, b = 18.485(6) angstrom, c = 19.334(7) angstrom, V = 4887(3) angstrom3, Z = 4; the final R value is 0.045; the crystal is built up from layer polymers; each neodymium ion is coordinated by four carboxylic oxygen atoms from four cystine molecules and four oxygen atoms from H2O, forming a coordination polyhedron of square antiprism. In the case of complex 2, the crystal belongs to the monoclinic space group C2/c, with unit cell parameters: a = 10.835 (11) angstrom, b = 22.27(2) angstrom, c = 25.85(3) angstrom, beta = 93-10(8)-degrees, V = 6227(10) angstrom3, Z = 4; the final R value is 0.069. The complex 2 is a binuclear molecule in which four carboxylic oxygen atoms of phenylalanine ligands and four oxygen atoms of water molecules form a distorted square antiprism around each neodymium ion.; Chemistry, Physical; Materials Science, Multidisciplinary; Metallurgy & Metallurgical Engineering; SCI(E); 6
