K2MCl5(M=La-Dy) and Rb2MCl5(M=La-Eu): Ino-chlorides with seven-coordinated rare earths

  • 1. Giessen Univ. (Germany, F.R.)

Description

K2PrCl5 crystallizes with a = 1263.1(8), b = 875.6(3), c = 797.3(4) pm, Z = 4, orthorhombic, Pnma, isotypic to e.g. Y2HfS5. Monocapped trigonal prisms (C.N. = 7) are connected to chains via common edges in [010] direction according to /sub infinity/1[PrCl/sub 3/1//sup t/Cl/sub 4/2//sup k/]2- with d-bar(Pr-Cl) = 281 pm. The chlorides K2MCl5 (M = La-Dy) and Rb2MCl5 (M = La-Eu) are isotypic to K2PrCl5. Thermal expansion of Rb2PrCl5 in [010] direction is remarkably smaller than parallel to (010). (author)
