摘要：

Colourless single crystals of 2 DyCl3 . dibenzo-18-crown-6 . CH3CN are obtained upon reaction of DyCl3 or KDy2Cl7 with dibenzo-18-crown-6-ether in acetonitrile. The crystal structure (triclinic, P1BAR, Z = 2; a = 1 105.6(2); b = 1 144.5(3); c = 1 367.8(3); alpha = 93.46(1); beta = 92.27(1); gamma = 117.45(1); R = 0.046; R(w) = 0.033) contains cationic and anionic edge-connected dimers according to [Dy2(dibenzo-18-crown-6)2Cl4]2+[Dy2(CH3CN)2Cl8]2- where Dy1 and Dy2 are coordinated by 3 and 5 chloride ions, respectively.
