(3,5-Dimethyl-1H-pyrazol-1-yl)tri-methyl-silane.

ABSTRACT

The title compound, C8H16N2Si, crystallizes in the the ortho-rhom-bic space group P212121 with one mol-ecule in the asymmetric unit. The Si-N bond is 1.782 (2) Å, which is substanti-ally longer than is found in comparable (3,5-di-methyl-pyrazol-yl)silanes. The tri-methyl-silyl group adopts a staggered conformation with respect to the planar 3,5-di-methyl-pyrazolyl unit. C-H⋯N hydrogen bonds between neighboring mol-ecules form a strand of mol-ecules along the b-axis direction.
