Abstract

The cocrystal of 1,2-Bis(diphenylphosphinoyl)ethane (DPPEO) with hydroquinone (HQ) (1:1) were studied theoretically with MINDO/3, MNDO, PM3 and AM1 semi-empirical methods to elucidate its structure. The bond lengths and angles from theoretical studies of molecule DPPEO/HQ (1:1) were found to be as expected. Theoretical results, concerning with intermolecular van der Waals forces in cocrystal, were compared with the previously obtained experimental data and AM1 results were found to be the best fit for selected C–C, C–P and P–O bond lengths and angles of DPPEO/HQ. For the hydrogen bond geometry AM1 results were found to be comparable with experimental data for the molecule without concerning van der Waals contacts.
