Abstract

Abstract: The reaction of the ambidentate ligand 1, 3‐bis(3‐methylpyridin‐2‐yl)thiourea (1 ) with [PtCl2 (dmso)2 ] in dichloromethane led to formation of a poorly soluble compound 2, characterized as a conventional chelate complex [PtCl2 (1 )]=2 . Reaction in methanol resulted in desulfurization to produce a fluorescing cationic diaminocarbene−platinum(II) complex 3, the structure of which was elucidated by X‐ray crystallography, mass spectrometry and NMR. Experimental findings were supported by DFT calculations. Abstract : The precursor compound [PtCl2 (dmso)2 ] reacts with 1, 3‐bis(3‐methylpyridin‐2‐yl)thiourea 1 either to an N, S‐coordinated chelate complex (in CH2 Cl2 ) or, in CH3 OH, to the carbene species 3 under desulfurization.
