Cationic and Anionic Edge-Connected Dimers in [Dy2(dibenzo-18-crown-6)2Cl4][Dy2(CH3CN)2Cl8]. Synthesis and Crystal StructureColourless 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, P1, Z = 2; a = 1 105.6(2); b = 1 144.5(3); c = 1 367.8(3); α = 93.46(1); β = 92.27(1); γ = 117.45(1); R = 0.046; Rw = 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.
Notes:
Bei der Umsetzung von DyCl3 oder KDy2Cl7 mit Dibenzo-18-Krone-6-Ether in Acetonitril werden farblose Kristalle der Zusammensetzung 2 DyCl3 · Dibenzo-18-Krone-6 · CH3CN erhalten. Die Kristallstruktur (triklin, P1, Z = 2; a = 1 105,6(2); b = 1 144,5(3); c = 1 367,8(3); α = 93,46(1); β = 92,27(1); γ = 117,45(1); R = 0,046; Rw = 0,033) enthält kationische und anionische, jeweils kantenverknüpfte Dimere gemäß [Dy2(Dibenzo-18-Krone-6)2Cl4]2+ [Dy2(CH3CN)2Cl8]2+, in denen Dy1 und Dy2 gegenüber Cl- die Koordinationszahlen 3 bzw. 5 aufweisen.
