Aurophilic interactions in mu-p-phenylenediethynyl-bis[(trimethyl phosphite)gold(I)] dichloromethane hemisolvate.
The title compound, [Au2(C10H4)(C3H9O3P)2].0.5CH2Cl2, is a linear monomer in which each Au atom is coordinated by one acetylene and one phosphite group. Molecules are connected through aurophilic interactions, one short and one longer, approximately perpendicular to the intramolecular di(gold acetylide) unit, with an Au...Au(x, 1 - y, (1/2) + z) distance of 3.1733 (2) A and an Au...Au(-x, y, (1/2) - z) distance of 3.5995 (3) A. Comparison with related compounds exhibiting aurophilic interactions shows that the packing architecture is not determined by steric factors alone.
