Tris[diphenyl(4-tolyl)phosphane]-1κ2P,2κP-μ-di-iodido-1:2κ4I-dicopper(I)

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 Cu⋯Cu 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.
