Tris[diphenyl(4-tolyl)phosphane]-1²P,2P--di-iodido-1:2⁴I-dicopper(I)

G. Steyl

Abstract: The title complex, [Cu₂I₂(C₁₉H₁₇P)₃], was obtained by refluxing two equivalents of P(4-TolPh₂) (4-Tol is 4-tolyl) with one equivalent of CuI in acetonitrile. Two distinct copper(I) centres are bridged by two iodide atoms with a CuCu separation of 2.7807 (9) Å, one with a trigonal coordination geometry and one Cu-P bond of 2.2209 (11) Å, and the second with a distorted tetrahedral coordination geometry and two Cu-P bonds of 2.2562 (12) and 2.2601 (11) Å. No hydrogen bonding, intercalation or stacking interactions were found in the crystal structure. One I atom is disordered over two positions, with occupancies of ca 0.79 and 0.21, and the H atoms of the methyl groups are each disordered equally over two positions.
