| Abstract: | Ligand exchange reactions of NMe4]TeCF3 and CuBr, AgBF4] and AuCl have been studied in molar ratios of 2:1. While evidence is found for Cu(TeCF3)2]− moieties by 19F-NMR spectroscopic and mass spectrometric means, NMe4]Ag(TeCF3)2] and NMe4]Au(TeCF3)2] were isolated. After cation exchange, the latter compounds were fully characterised as the PNP] salts (PNP] = bis(triphenylphosphoranylidene)ammonium). The single crystal structure of PNP]Au(TeCF3)2] has been elucidated by XRD measurements (P21/a; a = 1765.6(1), b = 1126.0(1), c = 2055.2(1) pm; β = 111.98(1)°; Z = 4). |
