Lamotriginium dihydrogen phosphate-4-(dimethylamino)benzaldehyde (1/1)

Abstract

In the title compound, C9H8Cl2N5+center dot H2PO4-center dot C9H11NO [systematic name: 3,5-diamino-6-(2,3-dichlorophenyl)-1,2,4-triazin- 2-ium dihydrogen phosphate-4-(dimethylamino)benzaldehyde (1/1)], intermolecular N-H center dot center dot center dot O and O-H center dot center dot center dot O hydrogen bonds produce R-2(2)(8) and R-3(2)(8) rings, generating a layer. Intermolecular N-H center dot center dot center dot N interactions also occur. The dihedral angle between the rings in the cation is 71.73 (12)degrees.
