  • Description: The interaction between the dinuclear chelate ring complex [Pt(μ‐Cl)(iPrEug)]2 (1) (iPrEug: deprotonated isopropyl eugenoxyacetate) and 1,3‐diisopropylbenzimidazolium bromide (iPr2‐bimy·HBr) has been studied for the first time. The result shows that the chloride bridges in 1 are easily cleaved by the iPr2‐bimy in the present of base to form a mixture (Phh) of two complexes [PtBr(iPrEug)(iPr2‐bimy)] (2) and [PtCl(iPrEug)(iPr2‐bimy)] (3), and the molar ratio of 2:3 in Phh depends on the used base Ag2O or Na2CO3/NaOOCCH3/NaHCO3/NaOH. The reaction of Phh with NaBr afforded complex 2 with high yield. The structure of 2 was determined by weight method, ESI‐MS, IR, 1H NMR, 13C NMR, HSQC spectroscopies and single‐crystal X‐ray diffraction. The NMR and XRD studies also reveal that the introdution of iPr2‐bimy leads to a weakening of the Pt‐(C9=C10) bond and strengthening of the Pt‐C5 bond in 2.
