enantiomers of each other. The two hexanuclear clusters exhibit two orthogonal linear trinuclear units. The two pairs of tridecanuclear clusters display esthetic structures with different symmetries; they feature rare heptanuclear vertex-sharing dicubane cores and their six unshared CuII vertexes are linked to another six CuII ions. These represent the first examples of chiral clusters bearing dicubane cores
(2R,3R)- 和 (2S,3S)-2,3-二羟基丁二酰肼与水杨醛和 3-甲氧基水杨醛的缩合反应得到两个对映体对,(2R,3R)/(2S,3S)-2,3-二羟基丁二酰双(水杨醛腙) [(2R,3R)-BSH 和 (2S,3S)-BSH] 和 (2R,3R)/(2S,3S)-2,3-二羟基丁二酰基双(3-甲氧基水杨醛腙) [(2R,3R)- MBSH 和 (2S,3S)-MBSH]。它们与 CuII 盐的反应提供了两个手性六核簇 [Cu6L2(C5H5N)10]2[C5H6N]3(ClO4)7·(CH3OH)·(C5H5N)[L = (2R,3R)-BSH; (2S,3S)-BSH] 和四个手性十三核簇 [Cu13L3(OH)2(CH3COO)6(C5H5N)6(DMF)3]·6DMF·3H2O [L = (2R,3R)-BSH;(2S,3S)-BSH] 和 [Cu13X3(OH)2(CH
