The title compound, C(2)H(10)BCl(2)N(2) (+)·Cl(-) or [BCl(2)(H(3)CNH(2))(2)](+)·Cl(-), is the first crystallographically characterized di(alkyl-amine)-BCl(2) (+) salt. The B atom is tetra-hedrally coordinated by two Cl and two methyl-amine N atoms. In the crystal structure, the cations and anions inter-act via N-H⋯Cl hydrogen bonds (mean H⋯Cl = 2.40 Å), resulting in a layered structure.
