Spectral Investigations of Co (II) Tetra Seleniazide Complex

Govind Kumar Gupta and S. P. S. Jadon

Se4N3Br a donor was refluxed with CoCl2 in DMF for 6-8 h. The brownish black coloured product was obtained, which was analysed qualitatively and quantitatively. The Br- was found absent. The quantitative analysis is also supported by Mass and IR spectra. The complex was assigned as structure (Se4N3)4CoCl2, where Co has coordidentated hexadentately with Se4N3 group through its N-atom.
