Abstrakt: The title compound [systematic name: 4-(di­methyl­amino)­pyridine–4-meth­oxy­phenyl­borane (1/1)], C14H19BN2O, contains two independent mol­ecules in the asymmetric unit. Both molecules exhibit coplanar, mostly sp2-hybridized meth­oxy and di­methyl­amino substituents on their respective aromatic rings, consistent with π-donation into the aromatic systems. The B—H groups exhibit an intra­molecular 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···π(arene) inter­actions between two of the H atoms of an amino­methyl group and the meth­oxy-substituted benzene ring of the other independent mol­ecule, and another C—H···π (arene) inter­action between one of the pyridine ring H atoms and the same benzene ring.
