Mononuclear, square-planar platinum(II) complexes having general formula cis-[PtI2(L)2], where L = 7-isobutyl-5-methyl-1,2,4-triazolo[1,5-a]pyrimidine (ibmtp) (1), 5,7-diethyl-1,2,4-triazolo[1,5-a] pyrimidine (detp) (2), 5,6,7-trimethyl-1,2,4-triazolo[1,5-a]pyrimidine (tmtp) (3) and 5-methyl-1,2, 4-triazolo[1,5-a]pyrimidin-7(4H)-one (HmtpO) (4) have been synthesized and characterized by infrared and multinuclear magnetic resonance (H-1, C-13, N-15, Pt-195) spectroscopy. The solid-state structure of cis-[PtI2(dptp)(2)].2dmf (5) has been determined by X-ray diffraction method. X-ray structure and spectroscopical parameters revealed that the heterocyclic ligands are coordinated to platinum(II) ion via N(3).
