"The synthesis, structure and reactivity of organoantimony(III) and organobismuth(III) compounds containing different types of O,C,O chelating, so called pincer, ligands (L = 2,6-(ROCH2)2C6H3-) comprise aims of this project. Two sets of compounds LnMX3-n (n = 1, 2; X = polar groups such as halogen, karboxylate etc.; M = Sb, Bi) and derivatives of the type LnMR3-n (n = 1, 2; R = various organic substituents bound to the central metal atom through direct M-C bond; M = Sb, Bi) should be prepared and characterized. The structure of these complexes will be investigated both in solution (NMR spectroscopy, IR) and in the solid state (X-ray diffraction analysis of single crystalline material), with the aim to describe the strength of intramolecular M-O interaction and to study the influence of this interaction on coordination polyhedron of central metal. The reactivity and stability of M-X bonds in LnMX3-n compounds will be investigated in the second part of this project with effort to prepare"@en . "antimony" . . . "0"^^ .
