Antimony(iii) and bismuth(iii) amides containing pendant N-donor groups – a combined experimental and theoretical study†
Abstract
N,N- and N,N,N-chelated antimony(III) and bismuth(III) chlorides L1–3MCl21–4 [for L1: M = Sb (1), for L2: M = Sb (2) and for L3: M = Sb (3) and Bi (4)], containing ligands L1–3 derived from the pyrrole ring (where L1 = C4H3N-2-(CH![[double bond, length as m-dash]](https://www.rsc.org/images/entities/char_e001.gif)
N-2′,6′-iPr2C6H3), L2 = C4H2N-2,5-(CH2NMe2)2, L3 = C4H2N-2,5-(CH2NC4H8)2), were prepared by the treatment of lithium precursors with SbCl3 or BiCl3. Molecular structures of 1–4 were described both in solution (NMR spectroscopy) and in the solid state (single-crystal X-ray diffraction analysis). Structures of 1–4 were also subjected to a density functional theory study.
