- Aryltin chlorides and hydrides: Preparation, detailed NMR studies and DFT calculations
-
A series of novel tin chlorides RnSnCl4-n and respective hydrides RnSnH4-n were synthesized displaying a range of substituted phenyl residues, as well as naphthyl moieties (R = Ph, o-tolyl, 2,4-xylyl, 2,6-xylyl, p-biphenyl, 1-naphthyl, 2-naphthyl). These compounds were characterized using 1H, 13C and 119Sn NMR spectroscopy. In addition, X-ray diffraction was employed to elucidate the molecular structure of all solid aryltin chlorides (8e10, 14, 15). In each case, the tin is in a distorted tetrahedral environment. All naphthyl containing derivatives exhibit displaced π-π stacking. DFT calculations were carried out to compare experimental NMR data with calculated 13C and 119Sn shifts, as well as 13C-119Sn coupling constants.

- Synthesis and Structural Assessment of Dipseudohalidobis-(p-biphenyl)tin(IV) Complexes
-
Dipseudohalidobis(p-biphenyl)tin(IV) compounds of the type (p-C6H5-C6H4)2SnX2 (X=NCS-, :NCO-, NCSe-, N3-) have been prepared and characterized by elemental analyses, molar conductance measurements and ir spectroscopic studies.Conductivity data suggest them to be nonelectrolytes in nitrobenzene.IR spectra of the compounds suggest that NCS(-), NCO(-) or NCSe(-) group is N-bonded to tin atom probably forming a bridged hexacoordinated structure in the solid state.
