A group of novel aryltin chlorides, bromides and hydrides (Ar nSnY4-n) (Ar = o-tolyl, 2,6-xylyl, 1-naphthyl, 2-naphthyl, p-n-butylphenyl; Y = Cl, Br, H) have been synthesized and structurally characterized via X-ray diffraction.These compounds display noncovalent intermolecular interactions in the form of edge to face, π-π stacking and C-H···π interactions resulting in discrete arrangements in the solid state.The strength of these interactions and their effect on resulting structural parameters, as well as the consequence of the aromatic substituent on the type of interactions present, will be highlighted and discussed.

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.

Cyclotristannathianes (4) are obtained from R2SnCl2 (1) and Na2S*9H2O or (CH3)3SiSSi(CH3)3.Analogously, hexathiatetrastannaadamantanes are prepared from RSnCl3(2) and the sulfenylating agents mentoined before.The reaction between dimesityltin dichloride (1a) and Na2S*9H2O depending on the reaction conditions yields either the corresponding dithiadistannacyclobutane (3) or cyclotristannathiane 4a.The structure of the cyclostannathianes 3, 4, and 5 are elucidated by determining the intensity ratio of geminal 119Sn-117Sn couplings.Calculated data are confirmed by experimental values.Additional proof is provided by measuring the change of intensity ratio in the 117Sn-NMR spectrum of 4c.X-ray structure determination proved for (C6F5Sn)4S6 (5g) to have the same geometry as in solution.
