Synthesis and crystal structures of two new Schiff base hydrazones derived from biphenyl-4-carbohydrazide

10.1007/s10870-011-0118-3

The study focuses on the synthesis and crystal structures of two novel Schiff base hydrazones derived from biphenyl-4-carbohydrazide. The compounds synthesized are N-[(E)-(2,5-dimethoxyphenyl)methylidene]biphenyl-4-carbohydrazide (1) and N0-[(E)-(4-fluorophenyl)methylidene]biphenyl-4-carbohydrazide (2). These compounds are the first structurally characterized biphenyl derivatives of phenylmethylidenecarbohydrazide. The study uses X-ray diffraction to determine their crystal structures, revealing that both compounds crystallize in monoclinic space groups but exhibit different molecular conformations due to the presence or absence of substituents in the ortho position of the phenyl ring.
