Bis(trifluoromethylselenato(0))metallates(I) of Silver and Gold, [M(SeCF3)2]− (M = Ag, Au)

Abstract Ligand exchange reactions of [NMe 4 ]SeCF 3 or [Cs(15‐Crown‐5) 2 ]SeCF 3 with Ag[BF 4 ] and AuCl gave the corresponding bis(trifluoromethylselenato(0))metallates [Ag(SeCF 3 ) 2 ] ‐ and [Au(SeCF 3 ) 2 ] ‐ in good yields. All compounds were characterized by NMR spectroscopic means and ESI mass spectrometry. Cation exchange with [PNP]Cl ([PNP] = bis(triphenylphosphoranylidene)ammonium) yielded the corresponding [PNP] salts. The single crystal structure of [PNP][Au(SeCF 3 ) 2 ] was elucidated by XRD measurements (P2 1 /a; a = 1712.0(1), b = 1142.5(1), c = 2013.6(1) pm; β = 112.10(1)°; Z = 4).
