Crystal structure of borated N,N,N',N'-tetra-methyldi-amino-methane.

In the title compound, {[(di-methyl-amino)-meth-yl]di-methyl-amine}-trihydridoboron, C5H17BN2, the tetra-hedral geometry of the N-C-N unit is slightly disorted. As a result of the bulky amine substituents, a wider N-C-N angle of 113.6 (1)° is observed. The bond lengths between the N atom and methyl groups are slighly elongated to 1.481 (2) and 1.482 (2) Šat the borated N atom, whereas the distances between the other N atom and its methyl groups are only 1.461 (2) and 1.462 (2) Å. The studied crystal was twinned. The twin data refinement was subsequently carried out with a scale factor of 0.263 (1). The two lattices of the twin domains were rotated by 179.84°.
