Crystal structure and Hirshfeld surface analysis of N-{[diphen­yl(vin­yl)sil­yl]meth­yl}-2-methyl­propan-2-ammonium chloride

N-{[Diphen­yl(vin­yl)sil­yl]meth­yl}-2-methyl­propan-2-amine, C(19)H(25)NSi, is a newly synthesized secondary amino­methyl­silane that can be used, for example, to study carboli­thia­tion reactions of vinyl­silanes. Because the neutral compound did not crystallize well, the hydro­chloride salt, C(19)H(26)NSi(+)·Cl(−), was formed, in which the two chloride ions in the asymmetric unit have crystallographic [Image: see text] site symmetry. An unusually long Si—C bond of 1.9117 (10) Å is observed in the cation, which may be ascribed to electronic effects due to the β N(+) species. In the crystal, the cations and anions are linked by N—H⋯Cl hydrogen bonds to generate [001] chains. To further investigate the inter­molecular inter­actions, a Hirshfeld surface analysis was performed, which showed that H⋯H, C⋯H/H⋯C and H⋯Cl/Cl⋯H contacts contribute 70.4, 20.0 and 8.3%, respectively.
