Abstract The indium tris (amide) s [(Et 2 N) 3–n In {N (C 6 F 5)(2-C 5 H 4 N)} n][n= 1 (15), 2 (16) or 3 (9)] have been prepared by treatment of [In (NEt 2) 3] 2 (3) with a stoichiometric amount of (2-C 5 H 4 N)(C 6 F 5) NH (1). The analogous reaction of Bi (NMe 2) 3 (2) with 3 equiv. of amine 1 and the treatment of BiCl 3 (5) with a stoichiometric amount of (2-C 5 H 4 N)(C 6 F 5) NLi (4) both lead to [Bi {N (C 6 F 5)(2-C 5 H 4 N)} 3](10). In contrast, only the ...
