Synthesis and structural characterization of a gold(I) complex containing 1,3-dimethylcyanurate ligand

Abstract

The gold(I) complex [Au(DMC)(PPh3)] (1) (DMC = 1,3-dimethylcyanurate) was synthesized and characterized by elemental analysis, FT-IR, 1H, 13C, 31P NMR and FAB mass spectroscopies. The structure of the complex was determined by X-ray diffraction and crystallizes in the triclinic space group P−1 with Z = 2. The gold(I) ion in complex 1 is coordinated by DMC ligand and PPh3 ligand, resulting in a slightly distorted linear structure. Molecules of 1 are connected via intermolecular CH···O hydrogen bonds, which lead to the formation of supramolecular network. Other intramolecular interactions which include Au···O contacts [Au···O25 3.045(1) and Au···O29 3.164(1)Å] were observed.
