Square Planar

Reaction of square planar [PtII(C≡CPh)(tpy)]+ (tpy = 2,2′:6′,2′′-terpyridine) with bromine at low temperature provides a general route for the synthesis of octahedral alkynyl(terpyridine)platinum(IV) complex. In this first example of alkynyl(terpyridine)platinum(IV) complex, the alkynyl group is situated in trans position relative to the central nitrogen atom of the terpyridine ligand, and the two bromido ligands are situated in trans positions; an X-ray structural analysis has been completed for trans(Br)-[PtIVBr2(C≡CPh)(tpy)]+.

Phenanthroline Ligand

A gold(III) salt of composition [AuCl2(C12H8N2)]PF6was 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 AuIIIcomprises the bidentate 1,10-phenanthroline ligand and two chloride ions, with the AuIIIion 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 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...π interactions that are a crucial factor for the crystal packing.
