title: Lamotriginium dihydrogen phosphate-4-(dimethyl-amino)-benzaldehyde (1/1).
abstract: In the title compound, C(9)H(8)Cl(2)N(5) (+)·H(2)PO(4) (-)·C(9)H(11)NO [systematic name: 3,5-diamino-6-(2,3-dichloro-phen-yl)-1,2,4-triazin-2-ium dihydrogen phosphate-4-(dimethyl-amino)-benz-alde-hyde (1/1)], inter-molecular N-H⋯O and O-H⋯O hydrogen bonds produce R(2) (2)(8) and R(3) (2)(8) rings, generating a layer. Inter-molecular N-H⋯N inter-actions also occur. The dihedral angle between the rings in the cation is 71.73 (12)°.
