eng	Intramolecularly coordinated organoantimony(III) carboxylates	The reactions of organoantimony chlorides L1,2SbCl2 1 and 2 ([2,6-(ROCH2)2C6H3]-, R = Me; L1 and R = t-Bu; L2) with silver salts of selected carboxylic acids resulted to corresponding organoantimony carboxylates L1,2Sb(O2CR)2, 1a-c (for L1) and 2a-c (for L2), where R = CH3 for 1a, 2a; R = CH-CH2 for 1b, 2b and R = CF3 for 1c, 2c. All compounds were characterized by the help of elemental analysis, ESI-MS, 1H and 13C NMR spectroscopy. The solid state structure investigation using single crystal X-ray diffraction techniques (2a, c) and IR spectroscopy revealed significant differences in coordination mode of both O,C,O chelating ligand and carboxylic groups in this set of compounds. The structure of all compounds in solution of non-coordinating solvent (CDCl3) was determined by means of variable temperature 1H, 13C, 19F NMR spectroscopy and IR spectroscopy.	organoantimony compounds;YCY ligand;carboxylates
