Crystal structure and Hirshfield analysis of the 4-(di-methyl-amino)-pyridine adduct of 4-meth-oxy-phenyl-borane.


ABSTRACT: The title compound [systematic name: 4-(di-methyl-amino)-pyridine-4-meth-oxy-phenyl-borane (1/1)], C14H19BN2O, contains two independent mol-ecules in the asymmetric unit. Both molecules exhibit coplanar, mostly sp2-hybridized meth-oxy and di-methyl-amino substituents on their respective aromatic rings, consistent with ?-donation into the aromatic systems. The B-H groups exhibit an intra-molecular close contact with a C-H group of the pyridine ring, which may be evidence of electrostatic attraction between the hydridic B-H and the electropositive aromatic C-H. There appears to be weak C-H??(arene) inter-actions between two of the H atoms of an amino-methyl group and the meth-oxy-substituted benzene ring of the other independent mol-ecule, and another C-H?? (arene) inter-action between one of the pyridine ring H atoms and the same benzene ring.
