Synthesis and crystal structure of di-chlorido-(1,10-phenanthroline-?2N,N')gold(III) hexa-fluorido-phosphate.

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