Synthesis and structure of a 2 CuII 2 CuI constellation ligated by the new biimidazole, bis(1-methyl-4,5-diphenylimidaz-2-oyl)carbinol

Bhalla, Rajiv,Helliwell, Madeleine,Garner, C. David

, p. 921 - 922 (1996)

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)2Cu II(Nim)2 centre with a CuII...CuII separation of 2.998(4) A and two CuI(Nim)2 moieties ca. 5 A from the Cu2 centre, each with an N-Cu-N angle of 169.3(4)°.
