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.
