Abstract
Two new hydrazone compounds, 4-chloro-N′-(4-hydroxy-3-nitrobenzylidene)benzohydrazide monohydrate (1) and 4-chloro-N′-(4-hydroxy-3-methoxybenzylidene)benzohydrazide monohydrate (2), were synthesized and characterized by physico-chemical methods and single crystal X-ray diffraction. Compound 1 crystallizes in the monoclinic space group P21/c with unit cell parameters a = 23.257(3) Å, b = 4.829(1) Å, c = 12.763(2) Å, β = 96.017(2)°, V = 1425.5(5) Å3, Z = 4, R 1 = 0.0525, and wR 2 = 0.1120. Compound 2 crystallizes in the monoclinic space group P21/c with unit cell parameters a = 8.103(3) Å, b = 21.321(3) Å, c = 10.594(3) Å, β = 120.281(2)°, V = 1580.5(8) Å3, Z = 4, R 1 = 0.0480, and wR 2 = 0.1078. Both compounds contains a hydrazone molecule and a water molecule. The crystals of the compounds are stabilized by N–H···O, O–H···O, and O–H···N hydrogen bonds.
