Abstract
The 1,1,2-triphenylethanol molecule, Ph2(PhCH2)COH (1), forms centrosy mmetric dimers in the solid state. The shortest O ... O separation, 5. 837 (3) angstrom, is too long for any O-H ... O hydrogen-bond formatio n. Instead, there are O-H ... pi(arene) interactions between the hydro xyl group of one molecule and a phenyl group of a centrosymmetrically related molecule. The O ... C and H ... C distances between the hydrox yl group and the closest phenyl-ring C atom are 3.525 (4) and 2.73 (4) angstrom, respectively. These intermolecular contacts are the only dr iving force towards dimer formation in the solid state.
