The title Schiff base compound, C(14)H(11)ClN(2)O(3), was prepared by the reaction of 5-chloro-salicylaldehyde and 4-hydroxy-benzohydrazide. The mol-ecule exists in a trans configuration with respect to the methyl-idene group. The dihedral angle between the two benzene rings is 40.1 (2)°. An intra-molecular O-H⋯N hydrogen bond helps to stabilize the(More)
The title Schiff base compound, C(19)H(16)N(2)O(3), prepared by the reaction of 2-meth-oxy-1-naphthyl-aldehyde and 2-hydroxy-benzohydrazide, crystallizes with two independent mol-ecules in the asymmetric unit. Each mol-ecule exists in a trans configuration with respect to the methyl-idene group. The naphthyl ring system make dihedral angles of 65.0 (2)° and(More)
The mol-ecule of the title Schiff base compound, C(20)H(18)N(2)O(3), prepared by the reaction of 2-meth-oxy-1-naphthyl-aldehyde and 4-methoxy-benzohydrazide, exists in a trans configuration with respect to the imine group. The naphthyl ring system makes a dihedral angle of 71.4 (2)° with the mean plane of the benzene ring. In the crystal structure,(More)
