Abstract

The potassium indyl K[In(NONDipp)] ([NONDipp]2– = [O(SiMe2NDipp)2]2–, Dipp = 2,6-iPr2C6H3) reacts with Pn(NONtBu)Cl (Pn = pnictide = Sb, Bi) to afford complexes containing In–Pn bonds. X-ray crystallography confirms monomeric species with unsupported (discrete) In–Sb and In–Bi bonds between pyramidal pnictide atoms and distorted trigonal planar indium atoms. Computational analysis confirms that the Pn centres retain a lone-pair of electrons and show that the In–Pn covalent bond is formed from the overlap of a s-type orbital from indium with a p-type orbital from the pnictide.
