Platinum(II) and platinum(IV) chloro complexes with (RS)-1-(4-chlorophenyl)-4,4-dimethyl-3-(1Н-1,2,4-triazol-1-ylmethyl)pentan-3-ol

Resumo

Platinum(II) and platinum(IV) chloro complexes with (RS)-1-(4-chlorophenyl)-4,4-dimethyl-3-(1Н-1,2,4-triazol-1-ylmethyl)pentan-3-ol (L), namely, cis-[PtCl₂L₂], trans-[PtCl₂L₂], and trans-[PtCl₄L₂], were synthesized. The structures of their coordination cores and the coordination mode of the reagent to the metal ions via the N(4) atom of the triazole ring were determined by electronic, IR, and NMR ¹H and ¹³C spectroscopy. The ratio between treo and erythro diastereomers and the conformation of reagent L in the complexes were established from the complete assignment of signals in their NMR spectra.
