Abstract
An X-ray crystal structure analysis of the title compound (1) shows the following notable features of the silacyclopropene ring ∠CSiC = 43.5(1)°, ∠SiCC = 69.8(1) and 66.7(1)°, C–C = 1.349(3), and Si–C = 1.800(2)(remarkably short) and 1.839(2) A; significant deviation of the ring from C2 symmetry may be due to the effect of substituents on the carbon atoms.Keywords
