Synthesis, Crystal Structure, and Spectroscopic Studies of N-(4-Bromobenzylidene)-N′-(2-Pyridyl) Hydrazine Schiff Base Molecule

Abstract

A new Schiff base complex N-(4-bromobenzylidene)-N′-(2-pyridyl) hydrazine, C₁₂H₁₀N₃Br, has been synthesized and characterized by elemental analyses, mass, ¹H NMR, ultraviolet–visible (UV–VIS), and IR spectroscopy and single-crystal X-ray determination. The p-Br-benzene and pyridine rings are almost planar and the dihedral angle between the planes is 11.1(3)°. The crystal structure is stabilized by intermolecular N‒H…N‒Py hydrogen bonding interaction. X-ray diffraction analyses show that N-(4-bromobenzylidene)-N′-(2-pyridyl) hydrazine Schiff base molecule crystallizes in the monoclinic system, P2₁/c space group, a = 5.611(5) Å, b = 19.566(5) Å, c = 10.715(5) Å, β = 98.766(5)°, and V = 1162.60(12) ų.
