T. Mancilla et al., CRYSTAL AND MOLECULAR-STRUCTURE OF (N-]B) PHENYL [N-METHYLIMINODIACETATE-O,O',N] BORANE, Silicon, germanium, tin and lead compounds, 20(1), 1997, pp. 31-36
The title compound, C11H12BNO4, crystallizes in a trigonal crystal sys
tem, space group <R(3)over bar>, With two independent molecules A and
B in the asymmetric unit. These molecules show a bicyclooctane structu
re with different torsion angles of the junction, -22.3 degrees (C-12-
B-1-N-6-C-7) for A and 16.6 degrees (C-62-B-51-N-56-G(57)) for a and N
--> B coordination bond distances of 1.662 (3) and 1.673 (3) A,respec
tively. They are linked to one another by intermolecular interactions
C=O ..... H-CH.
