In the solid state, 4-methoxy-N'-(2,2,2-trichloroethanimidoyl)benzene-1-carboximidamide, C10H10Cl3N3O, (I), N'-(2,2,2-trichloroethanimidoyl) benzene-1-carboximidamide, C9H8Cl3N3, (II), 4-chloro-N'-(2,2,2-trichloroethanimidoyl) benzene-1-carboximidamide, C9H7Cl4N3, (III), 4-bromo-N'-(2,2,2-trichloroethanimidoyl) benzene-1-carboximidamide, C9H7BrCl3N3, (IV), and 4-trifluoromethyl-N'-(2,2,2-trichloroethanimidoyl) benzene-1-carboximidamide, C10H7Cl3F3N3, (V), display strong intramolecular N-H center dot center dot center dot N hydrogen bonding across the chelate ring and also intramolecular N-H center dot center dot center dot Cl contacts. Additional intermolecular hydrogen bonds link the molecules into chains, double chains or sheets in all cases except for compound (V). For compound (II), there are three independent molecules per asymmetric unit.
