Pyrazine based Pt(II) bis-alkynyl organometallic complexes: Synthesis, characterization, and cytotoxic effect on A549 human lung carcinoma cells

A facile and efficient synthesis of a series of five new pyrazine‐based organometallic complexes is being reported. The complexes ( 2 – 6 ) have been fully characterized. Molecules 2 , 3 and 6 were structurally characterized by single crystal X‐ray crystallographic analyses. Additionally, anticancer properties of these organometallic complexes have been studied against A549 human lung carcinoma cells. Biological studies suggest that complex 5...
