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-(CHdouble bond{,} length as m-dashN-2prime or minute{,}6prime or minute-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.
