Reaction of In(C6F5)3Et2O with Complexes of Copper and Silver Monochlorides with N,N′-Bis(isopropylphenyl)imidazol-2-ylidene

The reaction of In(C 6 F 5 ) 3 ·Et 2 O with NHC dipp ·CuCl and NHC dipp ·AgCl in dichloromethane at room temperature leads to the formation of the complex [(NHC dipp )Cu(μ-Cl) 2 In(C 6 F 5 ) 2 ] and the solvate [(NHC dipp ) 2 Ag] + · [In 2 (μ-Cl)(C 6 F 5 ) 6 ] – ·СH 2 Cl 2 [NHC dipp — N , N ′-bis(isopropylphenyl)imidazol-2-ylidene]. Structures of the obtained compounds were determined by the single crystal X-ray diffraction analysis. An increase in Lewis acidity due to the introduction of electronegative C 6 F 5 groups makes it possible to stabilize the binuclear anion [In 2 (μ-Cl)(C 6 F 5 ) 6 ] – .
