series of neutral pincer Pt(II) chloride complexes 3–7 were first synthesized via the reaction of 1,3-bis(N-substituted benzimidazol-2′-yl) benzene (bzimb) ligands 2a–e with K2PtCl4 in refluxing HOAc. By treatment of complex 3 with KI and aromatic terminal alkynes in methanolic NaOH, the Pt(II) iodide complex 8 and Pt(II) acetylide complexes 9–11 were then obtained. Cationic Pt(II) complexes 12–15 were
