چکیده
There are two independent mol-ecules in the asymmetric unit of the title compound, C(17)H(20)N(2)O(4), which differ slightly in the orientation of the phenyl ring and carbonyl groups with respect to the pyrazole unit. In the first mol-ecule, the dihedral angle between the phenyl and pyrazole rings is 68.99 (13)° while the two carbonyl groups make a dihedral angle of 72.1 (4)°. The corresponding values in the second mol-ecule are 68.54 (14) and 71.5 (4)°, respectively.

The title compound, C(20)H(26)N(2)O(5), was prepared in good yield (76%) through condensation of diethyl (4-meth-oxy-benz-yl)propane-dioate with 3,5-dimethyl-1H-pyrazole. The dihedral between the benzene and pyrazole rings is 83.96 (10)°. The crystal packing is stabilized by a C-H⋯O inter-action, which links the mol-ecules into centrosymmetric dimers.

In the title compound, C(22)H(27)NO(4), the mean planes of the two benzene rings form a dihedral angle of 73.54 (13)°. One of the methyl groups is disordered over two sites, with site occupation factors of 0.47 (15) and 0.53 (15). The crystal packing is controlled by van der Waals forces and a possible C-H⋯O inter-action, forming a chain running parallel to the a axis.

The title compound, C(24)H(19)N(5)OS·H(2)O, was synthesized by the reaction of 4-benzoyl-3-methyl-1-phenyl-pyrazol-5-one and 2-hydrazino-1,3-benzothia-zole. Proton transfer leads to the formation of a zwitterionic structure and the mol-ecule exists in the enolate form. The pyrazolone ring makes dihedral angles of 35.4 (3), 69.7 (3) and 40.1 (3)° with the 1-phenyl, indirectly bound phenyl and be...

In the title compound, C(27)H(30)N(3)O(3)P, the pyrazole ring is essentially planar [maximum deviation = 0.002 (2) Å] and it forms dihedral angles of 9.3 (1) and 40.2 (1)°, respectively, with the phenyl rings attached to the N and C atoms. In the crystal, pairs of centrosymmetrically related mol-ecules are linked into dimers by N-H⋯O hydrogen bonds.
