eng	Preparation of the stibinidenes and bismuthinidenes and their use as ligands for TM	Our group has recently succeeded in the synthesis and structural characterization of the first monomeric organoantimony(I) and organobismuth(I) compounds stabilized by coordination of the N,C,N-pincer type of ligand.1 The present work includes a comparison of the reduction of organoantimony(III) and organobismuth(III) compounds. The reduction of the N,C,N-chelated bismuth(III) chlorides [C6H3-2,6-(CH=NR)2]BiCl2 (where R = t-Bu, 2´,6´-Me2C6H3 and 4´-Me2NC6H4) gave monomeric N,C,N-chelated bismuthinidenes2. In contrast, the structure of the compounds resulting from the reduction of the N,C,Nchelated antimony(III) chlorides depends on the reducing reagent and the nature of stabilizing ligand. Thanks to these findings, we were able to obtain new monomeric stibinidenes and bismuthinidenes, which contain two electron lone pairs available for TM coordination (Figure 1). In this contribution, the reactivity of monovalent stibinidenes and bismuthinidenes with selected TM complexes will be presented.	stibinidenes; bismuthinidenes; ligands
