Preparation, characterization and molecular models of the co(II)‎, ni(II)‎ and cu(II)‎ complexes of tetradentate ligand triethylenetetramine

الملخص EN

Triethylenetetramine was reacted with Co (II), Ni (II), and Cu (II) in EtOH medium.

In each case solid crystalline product were precipitated out after adding SCN counter anion.

The complexes have been formulated by comparing C, H, N and metal analysis data.

UV-Visible and IR spectra of the complexes have been discussed.

The molecular model calculation suggests the trans geometry of the complexes.
