Insertion of organoindium carbenoids into rhodium halide bonds: revisiting a classic type of transition metal–group 13 metal bond formation

Insertion of the carbenoid group 13 metal species InCp*(Cp*= pentamethylcyclopentadienyl) and InC(SiMe3)3 into the Rh–Cl bonds of [{RhCp*Cl2}2] yields the new complexes [Cp*Rh(InCp*)3(Cl)2]1 and [Cp*Rh(mu2-Cl)2(InC(SiMe3)3)3]2, respectively, exhibiting novel cage-like intermetallic complexes with In–Cl–In bridges.
