| Abstract: | With the help of quantum mechanical calculations, the geometric structures and electronic structures of the closed‐shell systems Cl(AuPH3) and Cl(AuPH3) ]2 have been determined by DFT and MP2 methods. Experimental structure parameters of the title compounds were reproduced at Xα level. The Mulliken population and HOMO–LUMO gaps were examined. The intermolecular aurophilic interactions in Cl(AuPH3) ]2 were analyzed and decomposed. A positive BE value (no bonding) was calculated. When 2PC was added, each pair Au… Au interaction energy was about 83 kJ/mol. © 2008 Wiley Periodicals, Inc. Int J Quantum Chem, 2009 |
