A new polymeric gold(I) diisobutyl dithiophosphate (Dtph), [Au{SP(O- iso-CH)}] ( I), was preparatively obtained and characterized by C and P MAS NMR spectroscopy and X-ray diffraction (CIF file CCDC no. 977818). Diagrams of the χ statistic were constructed from the complete P MAS NMR spectra and used to calculate the P chemical shift anisotropy (δ = δ − δ) and the asymmetry parameter η = (δ − δ)/(δ − δ). The main structural unit of complex I is the noncentrosymmetric dinuclear molecule [Au{SP(O- iso-CH)}], in which the gold atoms are linked by two bridging ligands Dtph. The central cyclic structural fragment of the dimer [AuSP] is additionally stabilized by the intramolecular aurophilic interaction Au⋯Au. Further supramolecular self-organization of the complex involves intermolecular aurophilic bonds Au⋯Au that serve to unite adjacent dinuclear molecules [Au{SP(O- iso-CH)}] with different spatial orientations into the polymer chains ([Au{SP(O- iso-CH)}]). The thermal behavior of complex I was examined by synchronous thermal analysis under argon. The character of the thermolysis of the complex to reduced metallic gold as a final product was determined.
