The synthesis and crystal structure of 4-(2'-hydroxybenzoylhydrazinyl) benzal-5-methyl-2-phenyl-2, 4-dihydropyrazol-3-one (B-1) and 4-(2'-hydroxybenzoylhydrazinyl) ethylidene-5-methyl-2-phenyl-2,4-dihydropyrazol-3-one (B-2) are presented in this paper. The crystal structures were determined by X-ray single crystal diffraction study. Crystal structure of B-1 belongs to monoclinic system with space group C2/c. The unit cell parameters are a = 1.4201 (2) nm, b = 1.65542 (2) run, c = 1.8455(3) nm, beta = 10132(1)degrees, V = 4.2541(10) nm(3), Z = 8, D-c = 1.344 g/cm(3), mu = 0.094 mm(-1), F(000) = 1808, R = 0.0442, wR = 0.1037. The water molecules bridge the adjacent stacks by the hydrogen bonds leading to the formation of supramolecular compound with two-dimensional network structure along the ac side. The crystal structure of B-2 belongs to triclinic system with space group P (1) over bar. The unit cell parameters are a = 1.2120(2) nm, b = 1.2223 (2) mn, c = 1.4159(3) nm, alpha = 70.38 (1)degrees, beta = 74.91 (1)degrees, gamma = 63.64 (1)degrees, V = 1. 7549(5) nm(3), Z = 4, D-c = 1.326 g/cm(3), mu = 0.092 mm(-1), F (000) = 736, R = 0.0436, wR = 0.1076. The supramolecule with one dimensional chain structure was formed through hydrogen bonds along the a axis. The molecules piled the layered structure along the b axis due to intermolecular interactions.
