Crystal structure of 3-methyl-5-trimethylsilyl-1H-pyrazole
Abstract
The title compound, C7H14N2Si, crystallizes in a tetragonal space group and exists as an N—H...N hydrogen-bonded tetramer, formed around the crystallographic fourfold rotoinversion axis. The molecular identity is clearly the 5-trimethylsilyl-3-methyl-1H-pyrazole tautomer and the structure is isomorphous with that of 5-tert-butyl-3-methyl-1H-pyrazole [Foces-Foces & Trofimenko (2001). Acta Cryst. E57, o32–o34].
