摘要：

Two new divalent rare earth iodides A(4)EuI(6)(A=Cs, Rb) were synthesized by one-step methods and their crystal structures were determined by X-ray powder diffraction experiments. The structures of Cs4EuI6 and Rb4EuI6 belong to K4CdCl6-type (trigonal, S.G.: R (3) over bar c, Z= 6), and their cell parameters are a = 14.634(4) Angstrom, c = 18.376(1) Angstrom and a = 14.305(2) Angstrom, c = 17.580(6) Angstrom, respectively. Isolated [EuI6] octahedra formed by Eu and I atoms are the main structural feature. (C) 1997 Elsevier Science S.A.
