摘要

(E)-Phenyl 2-(3,4-dihydro-1(2H)-naphthalenylidine) hydrazinecarboxylate and (E)-phenyl (2,4-dichlorophenylmethylene) hydrazinecarboxylate were prepared by the condensation of 1-tetralone or 2,4-dichlorobenzaldehyde with phenyl hydrazinecarboxylate. Crystals of C_(17)H_(16)N _2O_2 3 are monoclinic, C2/c, a = 17.763(4) ?, b = 8.353(2) ?, c = 40.233(8) ?, Z = 16, V = 5,839(2) ? ~3, R_1 = 0.0448 and wR_2 = 0.1104 for reflections with I>2σ(I). Crystals of C_(14)H_(10)N _2O_2Cl_2 5 are orthorhombic, P2_12 _12_1, a = 8.288(3) ?, b = 14.082(2)?, c = 23.788(5)?, Z = 8, V = 2,777(1) ? ~3, R1 = 0.0815 and wR_2 = 0.2006 for reflections with I>2σ(I). The molecular packing in the crystal for both compounds is the result of N-H?O hydrogen bonding.
