A structural study of late transition metal diethylenetriamine complexes

The synthesis and X-ray crystal structures of u-fac-[Ni(dien)2](NO3)2, s-fac-[Ni(dien)2](tos)2, fac-fac-[(H2O)(dien)Ni(μ-Cl)2(dien)(H2O)]Cl2, s-fac-[Ni(dien)2][ZnCl4], mer-[Ni(dien)2][CdCl4] · H2O, fac-[Ni(dien)(H2O)3](tos)2 · (H2O), mer-[Cu(dien)(H2O)](tos)2, fac-[Zn(dien)(H2O)2](tos)2 (dien = bis(2-aminoethyl)amine = diethylenetriamine; tos = p-toluenesulfonate) are described. The mode of binding of the tridentate amine is examined in detail.
