The material described by SiH2 is alpha-like structured and crystallizes in the monoclinic P2_1/m space group. The structure is zero-dimensional and consists of ten 13825-90-6 molecules. Si(1,3) is bonded in a water-like geometry to two equivalent H(2,6) atoms. H(2,6) is bonded in a single-bond geometry to one Si(1,3) atom. is represented by the CIF file [CIF]
