Abstract

Full X-ray crystallographic data are reported for the Pt(II) cations cis-[PtCl(PEt₃)₂(MTMP)]⁺ (1) and cis-[PtCl-(PEt₃)₂(INN)]⁺, acetone monosolvate (3) of 2, MTMP = methyl(trifluoromethyl)pyrazole and INN = indazole, both as BF₄^- salts. The Pt-N distances are short compared with those in related cations at 1.95 (3) and 1.96 (3) Å, respectively. In 1 MTMP is bonded to Pt through N², i.e., complexation of 3-(trifluoromethyl)-5-methylpyrazole, while in 2 INN is bound via the N² nitrogen as expected. It is suggested on the basis of ¹³C NMR spectroscopy that neutral MTMP exists in solution as (3-CF₃)(5-CH₃)C₃N₂H₂. Accordingly, deprotonation of MTMP or INN provides access to the neutral pyrazolyl-Pt(II) complexes cis-Pt(PEt₃)₂L₂,¹³C and ³¹P NMR data for the first of which indicate that the product is an isomer in which the Me (rather than the CF₃) substituent of the MTMP heterocycle is closest to Pt.
