Dichloridobis(methyl­amine-κN)boron(III) chloride

The title compound, C2H10BCl2N2 +·Cl− or [BCl2(H3CNH2)2]+·Cl−, is the first crystallographically characterized di(alkyl­amine)–BCl2 + salt. The B atom is tetra­hedrally coordinated by two Cl and two methyl­amine N atoms. In the crystal structure, the cations and anions inter­act via N—H⋯Cl hydrogen bonds (mean H⋯Cl = 2.40 Å), resulting in a layered structure
