Stabilization of gold(III) with bis(pyrazol-1-yl)amine
摘要:
Bis(3,5-R(2)pyrazol-1yl)amine (R=H (L1), Me (L2), tBu (L3)) reacts with H[AuCl4] to form the three salts [AuL1][AuCl4](2) (1), [AuL2][AuCl4](2) (2) and [AuL3]Cl-2 (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 H-1 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 H-1 NMR spectrum indicated interactions of the amine proton with this two CH2 groups.
