The crystal structure properties of [SiH2Mes2] (Mes = 2,4,6-trimethylphenyl) are: monoclinic, space group C2/c with a = 13.221(6), b = 9.076(2), c = 13.448(5)Å, Z = 4, R1 = 0.054 and wR2 = 0.129 with 1727 reflections (I > 2σ(I)). The coordination geometry about Si is approximately tetrahedral with a C-Si-C angle of 114.14(11)°. There is π-π stacking interaction between the parallel aromatic rings.
