Synthesis and characterisation of stable carbene–indium(III) halide complexes

Unusual Tilted Carbene Coordination in Carbene Complexes of Gallium(I) and Indium(I)

“…7 NHCs are most well‐known for their ability to coordinate transition metals,8, 9 but a good number of main‐group complexes have also been reported 8. 10–12 Among those are a number of gallium(III)10, 13 and indium(III)14, 15 complexes, but no such compounds are known for gallium(I) and indium(I) to date. Previous attempts have led to the formation of dimerized M II species 16.…”

Adducts of Aluminum and Gallium Trichloride with a N‐Heterocyclic Carbene and an Adduct of Aluminum Trichloride with a Thione

“…Only adducts of a phosphanylsilylcarbene with MCl 3 (M = Al 2 , Ga 3 , In 4 ) were reported and the X‐ray single‐crystal structure of 3 was determined 8. From reactions of a NHC with InX 3 (X = Cl, Br) under different conditions, carbene adducts with a composition of 1:1 and 1:2 ratios as well as imidazolium salts of carbene‐stabilized indates were obtained and structurally characterized 9 …”

Bidentate N-heterocyclic carbene complexes of Group 13 trihydrides and trihalides

“…5 This suggests that the InX 3 , X = Cl or Br, fragments are stronger Lewis acids than InH 3 which only forms four-coordinate complexes with carbenes. We wished to explore the interaction of EtIBu t with a range of Group 13 halides to investigate any differences there may be between the resulting complexes and 5-7.…”
