Abstract

The reactions of 1,3-bis((diphenyl)phosphinoxy)benzene and PtCl2(L)2 (L = SMe2, OSMe2, C5H5N) gave the new pincer-type 1,3-bis((diphenyl)phosphinoxy)phenyl platinum (II) complex [η3-κP:κC:κP-C6H3-1,3-(OPPh2)2]PtCl (1). The reaction between compound 1 and 4-ethynyl‑2,1,3-benzothiadiazole in the presence of copper iodide lead to the new complex [C6H3-1,3-(OPPh2)2]Pt-C≡C-(4-C6H3N2S) (2) containing a terminal (4-benzothiadiazol‑2,1,3-yl)ethynyl ligand. The compounds were characterized by IR- and NMR‑spectroscopy. These spectroscopy data allow us to propose the molecular structures of 1 and 2. The electrochemical properties of the new complexes were studied, the outcomes of their redox-reactions were proposed
