SYNTHESIS AND BIOLOGICAL ACTIVITY OF NEW SERIES OF ORGANOTIN(IV) ESTERS WITH N,N-DIACETYLGLYCINE

Química Nova, 2016
A bioactive N,N-diacetylglycine (NNDAG) and new organotin(IV) complexes (OTCs) (1-7) were synthesized. Spectroscopic techniques were employed to characterize NNDAG and OTCs. FTIR was employed to verify N,N protection of glycine by acetyl groups.

Heptacoordination in Organotin(IV) Complexes: Spectroscopic and Structural Studies of 2,6-Diacetylpyridine bis(thiosemicarbazone)di-n-butyltin(IV) Chloride Nitromethane Solvate, [nBu2Sn(H2daptsc)]Cl 2?MeNO2 and of 2,6-Diacetylpyridine bis(semicarbazone)dimethyltin(IV) trans-Tetrachlorodimethylstannate(IV), [Me2Sn(H2dapsc)][Me2 SnCl4]

Journal of the Brazilian Chemical Society, 2002
Two new cases of heptacoordination in organotin(IV) complexes are described. Both possess pentagonal bipyramidal geometry and show the organic groups on the axial positions, with the ligands forming five bonds to tin(IV) on the equatorial plane.
