Stabilizing, non-covalent interactions in the solid state structure of novel aryltin hydrides and halogenides

Abstract

A group of novel aryltin chlorides, bromides and hydrides (Ar n SnY 4-n ) 2, 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, -stacking and C-H··· 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. Résumé: De nouveaux chlorures, bromures et hydrures d'arylétain (Ar n SnY 4-n ) (où Ar = o-tolyl, 2,6-xylyl, 1-naphthyl, 2-naphthyl ou p-n-butylphenyl, et Y = Cl, Br ou H) ont été synthétisés et leur structure été déterminée par cristallographie aux rayons X. Ces composées présentent des interactions intermoléculaires non covalentes de type bord-face, empilement et C-H···, qui conduisent à des arrangements distincts à l'état solide. La force de ces interactions, leur effet sur les caractéristiques structurelles qui en résultent et l'impact du substituant aromatique sur les types d'interaction présents, seront exposés et étudiés.

Preface for the Special Issue dedicated to the 14th International Conference on the Coordination and Organometallic Chemistry of Germanium, Tin and Lead (ICCOC-GTL 2013)

“…The purpose of this conference was to bring together researchers whose interests span the chemistry of germanium, tin, and lead, and this collection of manuscripts reflects the diverse range of topics presented at the conference: from the synthesis of low coordinate molecules as illustrated in the work presented by Jones 1 and studies of the reactivity of these interesting species as reported by Růžička, 2 Tokitoh 3 Willem, 4 and Baines 5 to the synthesis of high coordinate supramolecular structures as demonstrated in the work of Reuter; 6,7,8 from muon spin spectroscopy of germanium radicals as studied by West 9 to nuclear magnetic resonance spectroscopy 4 of Sn(II) and Sn(0) complexes; from the synthesis of ternary metal clusters as reported by Molloy 10 to polymers and their model oligomers as synthesized by Foucher 11 and Weinert, 12 respectively. Saito, 13 Shankar, 14 and Uhlig 15,16 describe their research on the high yielding synthesis and extended structures of several important functional tin(IV) compounds. Finally, the elegant synthesis of a mixed Group 14 propellane was reported by Breher.…”
