Abstract

Bis(3,5-R₂pyrazol-1yl)amine (R = H (L1), Me (L2), tBu (L3)) reacts with H[AuCl₄] to form the three salts [AuL1][AuCl ₄]₂ (1), [AuL2][AuCl₄]₂ (2) and [AuL3]Cl₂ (3) respectively. The composition of these salts was established via mass spectrometry and microanalysis and confirmed by single crystal X-ray studies for 2. Room temperature ¹H NMR spectrum of these salts after a D₂O wash showed two triplets for the inequivalent CH₂ groups in the ligand backbone, while prior to the D₂O washing the ¹H NMR spectrum indicated interactions of the amine proton with this two CH₂ groups.
