Abstract The molecular structure of (2,3-diazanorbornene)Fe3(CO)9 consists of a triangular Fe3(CO)9 group bound to the diazene unit. The seven-coordinated Fe(CO)3 group forms two Fe-N bonds with lengths of 1.974 and 1.965 Å, each of the two six-coordinated Fe(CO)3 groups has slightly shorter Fe-N-bonds of 1.898 and 1.903 Å. One Fe-Fe distance, 2.612Å, is longer than the two other ones, 2.572 and 2.582 Å, which are in the range of typical single bonds. The presence of seven-and six-coordinated iron carbonyl groups is also demonstrated by the Mössbauer spectrum showing signals with quadrupole splittings of 1.23 and 0.78, 0.62 ± 0.01 mm/s, respectively.

Pyridoxal Hydrochloride

New series of copper (II), cobalt (II), zinc (II), nickel (II), manganese (II), iron (II) complexes of a novel Schiff base were prepared by the condensation of sulphadizine and pyridoxal hydrochloride. The ligand and metal complexes were characterized by utilizing different instrumental procedures like microanalysis, thermogravimetric examination and spectroscopy. The integrated ligand and transition metal complexes were screened against various bacteria and fungus. The studies demonstrated the enhanced activity of metal complexes against reported microbes when compared with free ligand.
