This compound, C24H20FeN2O4, crystallizes in the orthorhombic space group P2121 21 with unit cell parameters a= 8.911 ( 1 ), b=14.045 ( 1 ) ,c=16.259 ( 3 )A, V = 2034.8 (5 )A3,F(000)=944, μ(MoKα) = 7. 72 cm(-1). The calculated density is 1.49g/cm3 for Z=4. In contrast to most previously reported hydroxamic acids that have been structurally characterized, two planar hydroxamic acid groups are in trans with C(O))-N and C-O distances being similar to those found in amides. The stabilization of the trans-conformation of the title compound is ascribed to the steric and electronic interaction between two phenyl rings and strong hydrogen bond hetween the hydroxyl and carbonyl.展开更多
A new tripodal ligand containing ferrocenyl and hydrazone groups was synthesized by the condensation of ferrocenylcarbonylhydrazine with tris {[2 (2 formylphenyl)oxo]ethyl}amine and characterized by elemental analyses...A new tripodal ligand containing ferrocenyl and hydrazone groups was synthesized by the condensation of ferrocenylcarbonylhydrazine with tris {[2 (2 formylphenyl)oxo]ethyl}amine and characterized by elemental analyses, IR and 1H NMR. It is expected to be an important ligand to react with transition metals to give functional coordination complexes with interesting physical chemical properties. Studies on its reactions and properties are in progress.展开更多
