The reaction of the ambidentate ligand 1,3‐bis(3‐methylpyridin‐2‐yl)thiourea ( 1 ) with [PtCl 2 (dmso) 2 ] in dichloromethane led to formation of a poorly soluble compound 2 , characterized as a conventional chelate complex [PtCl 2 ( 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.
