The new biimidazole, bis(1-methyl-4,5-diphenylimidaz-2-oyl)carbinol, BimOH, is synthesized and employed to form the novel tetrameric constellation [Cu4(BimOH)2(BimO)2]4+, involving an (Nim)2CuII(OR)2CuII(Nim)2 centre with a CuII⋯ CuII separation of 2.998(4)Å and two CuI(Nim)2 moieties ca. 5 Å from the Cu2 centre, each with an N–Cu–N angle of 169.3(4)°.
新的双咪唑--双(1-甲基-4,5-二苯基咪唑-2-酰基)甲醇 BimOH 被合成并用于形成新的四聚体[Cu4(BimOH)2(BimO)2]4+,其中涉及一个 (Nim)2CuII(OR)2CuII(Nim)2 中心,CuII⋯CuII 间距为 2.998(4)埃,两个 CuI(Nim)2 分子距离 Cu2 中心约 5 埃,每个分子的 N-Cu-N 角为 169.3(4)°。
