The crystal structure of 1-p-bromophenylsilatrane was determined at ambient and low temperature. The methylene groups of the silatrane skeleton in the β-position to the nitrogen atom are disordered in the ambient temperature structure. The disorder disappears at 133 K. The Si mutually implies N dative bond length is nearly identical at both temperatures (2.139(3) and 2.132(2) A). The deviation of the atoms in the silatrane moiety from the ideal three-fold symmetry seems to point to the most dynamically behaving parts of the molecule.
