consists of the expected copper(II) dinuclear entities, with the perchlorate groups making additional bridges of either side of the macrocycle. The molecular skeleton is significantly bent in a boat fashion. The electrochemical properties of those two 4-tri- fluoromethyl substituted compounds have been investigated and compared to those of the 4-methyl substituted compounds [Cu2(L1CH3)](ClO4)2·2H2O
从最近描述2,6-二甲酰基-4-三氟甲基苯酚,我们已合成的化合物[铜2(L 1,2 CF 3)](CLO 4)2 · X ^ h 2 O.大号1 CF 3和L 2 CF 3是分别具有丙烯和丁烯侧链的4-三氟甲基取代的Robson型双核配体。解析了[Cu 2(L 1 CF 3)](ClO 4)2的晶体结构。该化合物在正交晶系,空间群中结晶Pbca:a = 9.537(4),b = 18.072(10),c = 34.340(11)Å,Z = 8周期的一面。分子骨架以船形显着弯曲。已经研究了这两个4-三氟甲基取代的化合物的电化学性质,并将其与4-甲基取代的化合物[Cu 2(L 1 CH 3)](ClO 4)2 ·2H 2 O和[Cu 2(L 2 CH 3)](二氧化氯4)2。替换CH的3由CF 3个移位所述第一还原波由CA。0.15 V,第二个大约为。比较了[Cu 2(L 1 CF 3)](ClO
