摘要：

Polychelating nitroxide ligands derived from N-methylethylenediamine and piperazine have been prepared by reactions of 2-bromomethyl nitronyl nitroxide with the corresponding polyamines. Two of these ligands have been structurally and magnetically characterized, along with some of their transition metal complexes, the magnetic properties of which are compared to those of previously reported related species. In particular, the properties of a nickel(II) derivative of a pentadentate tris(nitroxide), the ground spin-state of which is a quadruplet, are discussed in detail.
