The copper(I) halide adducts with tri-m-tolylphosphine are prepared and studied by spectroscopic methods. The crystal structure of [Cu2I2{P(m-tolyl)3}3] is reported. The title compound crystallizes in the P1 space group with a=17.729(1), b=13.682(2), c=24.635(3) (Γ…), Ξ±=117.769(4), Ξ²=104.966(4), Ξ³=107.536(3)Β° and Z=2. The versatility of the above adducts as revealed by the present and analogous compounds is investigated computationally using EHT calculations. These support the relative stability of the observed geometric arrangement in relation to ones where both copper atoms possess identical local environments, either trigonal planar or pseudotetrahedral provided that the phosphine bulk is not the determining factor in the complex formation.
