摘要：

[PrCl2(H2O)6]Cl, M(r) = 355.4, monoclinic, P2/n, a = 8.019 (3), b = 6.599 (3), c = 9.729 (2) angstrom, beta = 93.75 (2)degrees, V = 513.7 (7) angstrom 3, Z = 2, D(x) = 2.297 g cm-3, lambda(Mo K-alpha) = 0.71069 angstrom, mu = 54.86 cm-1, F(000) = 340, room temperature, R = 0.051 for 1233 observed reflections. The complex is isostructural with Nd, Sm, Gd, Dy and Lu analogues. The cation has C2 symmetry and the geometry around the eight-coordinated Pr(III) atom, located on a twofold axis, is a square antiprism. The Pr-Cl (coordinated) distance and the average Pr-O distances are 2.834 (2) and 2.472 angstrom, respectively.
