摘要：

The crystal structure of 2NdCl(3). galactitol . 14H(2)O has been determined. The crystal system is triclinic, space group: -1, with unit-cell dimensions: a = 9.736(2), b = 10.396, c = 8.027 Angstrom; alpha = 108.05(3), beta = 92.68(3), gamma = 88.44(3)degrees, V = 771.6(3) Angstrom (3), Z = 2. Each Nd atom is coordinated to nine oxygen atoms, three from the alditol and six from water molecules, with Nd-O distances from 2.461 to 2.552 Angstrom. The seventh water molecule is hydrogen-bonded by the hydroxyl hydrogen on O-1 (O-1-H-11 . . .O-10, 2.639 Angstrom). The FT-IR spectra of 2NdCl(3). galactitol . 14H(2)O and 2PrCl(3). galactitol . 14H(2)O are analogous, and show that Pr and Nd have the same coordination mode. The IR results are consistent with the crystal structures. (C) 2001 Elsevier Science Ltd. All rights reserved.
