The betain like carbodiphosphorane CO 2 adduct O 2 CC(PPh 3 ) 2 ( 1a ) can serve as a ligand versus hard Lewis acids from main group compounds. Thus, reaction of 1a with InCl 3 , InI 3 and SnCl 2 in polar solvents leads to the addition compounds [Cl 3 In{O 2 CC(PPh 3 ) 2 }] ( 2 ), [Cl 2 SnO 2 CC(PPh 3 ) 2 }] ( 3 ) and the salt like compound [I 2 In{O 2 CC(PPh 3 ) 2 } 2 ]I ( 4 ) in good yields. Whereas in the indium compounds 1a acts as a chelating ligand, in the tin compound the molecule coordinates with one oxygen atom only as a monodentate ligand. 4 has a pyramidal structure with a stereochemical active pair of electrons. All compounds could be characterized by X‐ray analyses and the usual spectroscopic methods.
