| description | A series of bis(phosphane)copper(I) thiocarbamates, namely
(Ph3P)2Cu[ROC(=S)N(H)Ph]Cl, were prepared in response to the promising biological
properties exhibited by the related phosphanegold(I) analogues. The presence of an
intramolecular N-H···Cl hydrogen bond in the title compounds, was found leading to the
formation of a six-membered quasi-chelate ring, {CuCl···HNCS}. Following ring closure,
unanticipated C–H···π(quasi-chelate ring) interactions were evidenced in one-third of
related copper(I) complexes capable of forming similar quasi-chelate rings. Computational
chemistry calculations revealed that these interactions when occurring intramolecularly,
afforded energies of attraction approximating 3.5 kcal mol-1. In a subsequent review of
analogous copper(I) complexes, intermolecular C–H…π(quasi-chelate) interactions
imparted stabilisation to the crystal structures, leading to zero-, one-, two- and even threedimensional
architectures. |
