Synthesis of new platinum(II) compounds with several bidentate and tridentate nitrogen-donor ligands. Structural analyses by 1H, 13C{1H} and 195Pt{1H} NMR spectroscopy and X-ray crystal structure

Neutral and ionic Pt(II) complexes of several N-alkylaminopyrazole ligands (NN′ and NN′N) have been prepared and characterised. 1H NMR spectroscopic studies of the complexes prove the rigid conformation of the ligands when they are complexed.
