eng	Double O,C,O-chelated diorganotin(IV) derivatives	Novel diorganotin(IV) compounds (L-1,L-2)(2)SnCl2 where L-1,L-2 are O,C,O-chelating ligands (called the pincer ligands), 2,6-bis(alkoxy-methyl)phenyl-, 2,6-(ROCH2)(2)C6H3-. (L-1, R =Me, L-2, R = t-Bu), have been synthesized and characterized by H-1, C-13 and Sn-119 NMR spectroscopy, MS-ES1 spectrometry and elemental analysis. The structure of both compounds (L-1)(2)SnCl2 (1) and (L-2)(2)SnCl2 (2) was determined by X-ray crystallography. Determination of crystal structures reveals different shapes of coordination polyhedra. While deformed octahedron was found for 1, tetrahedral geometry of the tin atom was determined for 2. The NMR spectroscopy indicates a similar structural arrangement of I and 2 in solution. The reaction of I with silver salts of low nucleophilic anions X- (X = OTf and 1-CB11H12) resulted in (L-1)(2)SnCl(OTf) (3), (L-1)(2)Sn(OTf)(2) (4), and (L-1)(2)SnCl(CB11H12) (5). The compounds 4 and 5 are of ionic nature both in solid state and ill Solution of CH3CN.
