Metal Complexes Derived from Isobutyric Acid Hydrazide with Some Bivalent Metal Ions

Abstract

Department of Chemistry, Faculty of Science, Mansoura University, Egypt Manuscript received 16 November 1983, accepted 10 August 1984 The preparation and characterisation of some new metal complexes derived from, isobutyric acid hydrazide (IBH), of the types [M(IBH)X₂]. [M(IBH)₂X₂(M = Co^II, Ni^II, Cu^ll, Zn^II, Cd^II and Hg^II ; X = CI, Br) and [M(IBH)₃X₂.H₂O] (M=Co^II, Ni^II, Cu^II, Zn^II and Cd^II) are reported. Infrared spectral data show that IBH acts as a monodentate ligand and coordinated via azomethine group (imidol structure). The stereochemistry of the isolated solid complexes have been discussed with the help of magnetic and spectral (electronic and nmr) measurements.
