设计了一种模板法合成可电离的14-、15-和16-元四氮杂、四烯大环配体。并报道了六配位双阳离子铁（II）配合物的合成。对于14元配体的反式二乙腈络合物，但对于15-和16-元配体，乙腈分子亲电添加到大环的y-碳，产生新的六齿配体的络合物。后者代表的例子，其中通过将两个供体基团附加到四齿大环配体上来实现配位饱和。这些结构形式上类似于细胞色素c等天然血红素蛋白。
A template synthesis of ionizable 14-, 15-, and16-membered tetraaza, tetraene macrocyclic ligands, devoid of functional substituents, has been devised. Also, the synthesis of six-coordinate dicationic iron (II) complexes of the new li-gands are described. For the 14-membered ligand a trans diacetonitrile complex was obtained, but for both the 15-and 16-membered ligands, acetonitrile molecules add electrophilically to the y-carbons of the macrocycle, producing the complex of novel sexadentate ligands. The latter represent examples in which coordinate saturation is achieved by the appending of two donor groups to a tetradentate macrocyclic ligand. These structures are formally analogous to such natural heme proteins as cytochrome c.
