(2-[4-Methylpyrazol-1-yl]phenyl)platinum(II) (1,3-bis[1-methyl-1<i>H</i>-pyrazol-4-yl]propane-1,3-dione)

Abstract

In this work, the title compound was synthesized via the reaction of an aryl-substituted pyrazole with potassium tetrachloroplatinate, followed by the reaction of the postulated intermediate chloro-bridged dimer with a pyrazole-containing 1,3-diketonate ligand. The structure of the synthesized complex was established by 1H, 13C NMR spectroscopy and mass spectrometry. According to UV-Vis spectrometry studies, the obtained complex exhibits green fluorescence with a maximum at 514 nm. Based on cyclic voltammetry studies, the HOMO, LUMO and band gap values were calculated.
