Abstract

A series of novel and previously published silicon dihydrides, R2SiH2 (R = benzyl, fluorenyl, p-tolyl, p-n-butyl, p-biphenyl, m-tolyl, o-tolyl, 2,4-xylyl, 2,6-xylyl, p-biphenyl, 1-naphthyl, 9-anthracenyl), were synthesized and characterized using H-1, C-13, and Si-29 NMR spectroscopy. Effects of substituent bulk on Si-29 NMR shifts are compared between reported silicon dihydrides species and novel dihydrides herein. In addition, single crystal X-ray diffraction was employed to elucidate the molecular structure of all solid silicon dihydrides and the at room temperature liquid p-tolyl(2)SiH(2). These compounds display non-covalent intermolecular interactions in the form of edge to face, pi-pi stacking, and CH3 center dot center dot center dot pi interactions. The dependency of substituent type on the nature of interactions present will be highlighted and discussed.
