Abstract

A gold(III) salt of composition [AuCl2(C12H8N2)]PF6 was prepared and characterized by elemental and mass spectrometric analysis (ESI(+)-QTOF-MS), H-1 nuclear magnetic resonance measurements and by single-crystal X-ray diffraction. The square-planar coordination sphere of Au-III comprises the bidentate 1,10-phenanthroline ligand and two chloride ions, with the Au-III ion only slightly shifted from the least-squares plane of the ligating atoms (r.m.s. = 0.018 angstrom). In contrast to two other previously reported Au-III-phenantroline structures that are stabilized by interactions involving the chlorido ligands, the packing of the title compound does not present these features. Instead, the hexafluoridophosphate counter-ion gives rise to anion center dot center dot center dot pi interactions that are a crucial factor for the crystal packing. (AU)
