Infrared spectra of matrix isolated dibridged Si(μ-H)2MH2 and tribridged Si(μ-H)3MH molecules(M = Zr and Hf,or Be and B) were observed following the laser-ablated metal atom reactions with SiH4 during condensation in excess argon and neon,but methylidene complex CH2=MH2 with agostic bonding was formed in metal atom reactions with CH4.
