Tris[2-(dimethylamino)phenyl]silane and -germane compounds (1 and 2) were synthesized and characterized by X-ray crystallography. Three 2-(dimethylamino)phenyl groups in the hydrosilane (1a) and hydrogermane (1b) encapsulate the hydrogen atom bonded to silicon and germanium, which results in the short Si−H and Ge−H bonds and an increase in the s character of the bonds. The silanol (2a) and germanol (2b) exist as monomers through the intramolecular hydrogen bonding between the hydroxy group and one of the amino groups.

Tris[2-(dimethylamino)phenyl]silane and -germane compounds (1 and 2) show promising properties in silane and germanol synthesis, with potential applications in silane and germanol-based polymers.
