STRUCTURES OF 2,6-BIS(AMINOMETHYL)PYRIDINE (BAMP) COMPLEXES OF FEII, NIII, ZNII, MNII, COIII AND CUII

The structures of bis[2,6-bis(aminomethyl)pyridine]iron dichloride hydrate [(I), Febamp], bis[2,6-bis(aminometh-yl)pyridine]nickel dichloride hydrate [(II), Nibamp], bis[2,6-bis(aminomethyl)pyridine]zinc dichloride hydrate [(III), Znbamp], bis[2,6-bis(aminomethyl)pyridine]manganese dichloride hydrate [(IV), Mnbamp], bis[2,6-bis(aminomethyl)pyridine]cobalt trichloride hemihydrate [(V), Cobamp] and chloro[2,6-bis(aminomethyl)pyridine]copper perchlorate [(VI), Cubamp] are reported. The bamP ligand complexes in a tridentate manner and except in the case of Cu(II), which is mono-tridentate coordinated, the complexes are all bis-tridentate. The Fe(II), Ni(II) and Zn(II) complexes are isomorphous. In general, the M-N(pyridine) distances are shorter than normal, while the M-N(amino) distances are slightly longer than normal.
