Abstract

The reaction of some first-row transition metal acetate salts with 4-amino-3,5-di(2-pyridyl)-1,2,4-triazole (adpt) gives crystals of interesting octa-, tetra-, di- and mononuclear metal complexes with a range of metal-ligand binding modes observed. Specifically, an octanuclear iron complex [Fe ₈(adpt^-H)₂(OAc)₁₁(O) ₄(OH)₂] was formed, with each deprotonated amine group bridging two iron centres; two different nickel acetate complexes [Ni ₂(adpt)(adpt^-H)(OAc)₃(H₂O)] and [Ni(adpt)₂(OAc)₂] co-crystallised in a 2:1 ratio, containing both adpt and adpt^-H ligands and exhibiting several different ligand binding modes, whereas reaction of zinc acetate with adpt gave a tetranuclear complex [Zn₄(adpt)₂(OAc) ₆(OH)₂] with the ligand remaining neutral.
