Synthesis and crystal structure of the derivants of hydrazide containing pyrazolone

The synthesis and crystal structure of PMBP-NTH and PMBP-PAH are presented in this paper. The crystal structures were determined by X-ray single cryst al diffraction. Crystal structure of PMBP-NTH belongs to triclinic system w ith space group P (1) over bar. The unit cell parameters are a = 0.9024(2) mn, b = 1.0953 (2) nn, c = 1.1635(2) nm, alpha =67.070(10)degrees, beta =68 .220(10)degrees, gamma =84.770(10)degrees, V=0.9816(3) nm(3), Z=2, D-c = 1. 345 g/cm(3), mu =0.090 mm(-1), F(000)=416. The crystal structure of PMBP-PA H belongs to monoclinic system with space group P(2)1/c. The unit cell para meters are a = 1.2715(4) nm, b = 0.91710 (10) nm, c=1.8979(3) nm, beta =106 .890(10)degrees, V=2.1177(8) nm(3), Z=4, D-c =1.338 g/cm(3), mu =0.090 mm(- 1), F (000) = 896, R = 0.0414, wR = 0.0972.
