Expanding the family of C,N-chelated organotin(IV) pseudohalides: Synthesis and structural characterization

Popis výsledku v původním jazyce

A set of tri- and diorganotin(IV) pseudohalides bearing the 2-(N, N-dimethylaminomethyl)phenyl-as a C,N-chelating ligand (L-CN) has been prepared and structurally characterized. Triorganotin(IV) pseudohalides of the type (LR2SnX)-R-CN [R = n-Bu, X = NCO (1a), NCS (1b), NCSe (1c), CN (1d); R = Ph, X = NCO (2a), NCS (2b), NCSe (2c), CN (2d)] and (L-CN)(2)(n-Bu)SnX [X = NCO (3a), NCS (3b), NCSe (3c), CN (3d)] are monomeric both in solution and the solid state. The central tin atom in these species is five-coordinated in the solid state with distorted trigonal bipyramidal geometry. Monomeric diorganotin(IV) pseudohalides of the type (L-CN)(2)SnX2 [X = NCO (4a), NCS (4b), NCSe (4c), CN (4d)] contain six-coordinated tin atoms with heavily distorted octahedral geometry both in solution and solid state due to the presence of two L-CN units. Finally, we have found that L-CN(n-Bu)Sn(NCS)(2) (5) is presumably dimeric in CDCl3 and monomeric in THF-d(8) or DMSO-d(6) solution while it forms infinite linear polymer in the solid state via thiocyanate bridges. According to IR, multinuclear NMR spectroscopy and XRD analysis, it was found that the pseudohalide ligands of the N=C=Y type (Y=O, S, Se) are bound via nitrogen while the CN substituent act as a common cyanide ligand (i.e. binds via carbon). DFT calculations were performed for selected compounds (2a, 2b, 2d and 4d) to further support our conclusions about the nature of the Snpseudohalide bonds. Compound (LSnPhI2)-Sn-CN (6), which was prepared in the scope of this work as well has a trigonal bipyramidal structure with non-equivalent iodine atoms.
