摘要：

Single crystals of [La2I2(OH)(2)(dibenzo-18-crown-6)(2)]I(I-3) are obtained from the reaction of LaI3 and dibenzo-18-crown-6 in acetonitrile. The crystal structure (monoclinic, C2/m, 2=4, T=293 [100] K, a=2179(3) [2162.3(3)], b=1070.3(3) [1069.6(1)], c=1118.2(3) [1110.6(1)] pm, beta=93.1(1) [92.83(1)]degrees, R1=0.0601 [0.0411], wR2=0.1449 [0.1014] contains hydroxide-bridged cationic dimers and iodide as well as triiodide as anions.
