[La2I2(OH)2(dibenzo-18-crown-6)2]I(I3), a Cationic Dimeric in-cavity Complex with Iodide and Triiodide as AnionsSingle crystals of [La2I2(OH)2(dibenzo-18-crown-6)2]I(I3) are obtained from the reaction of LaI3 and dibenzo-18-crown-6 in acetonitrile. The crystal structure monoclinic, C2/m, Z = 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, β = 93.1(1) [92.83(1)]°, R1 = 0.0601 [0.0411], wR2 = 0.1449 [0.1014] contains hydroxide-bridged cationic dimers and iodide as well as triiodide as anions.
