【 摘 要 】

The redetermination of the structure of the title compound, [Fe(C15H12N4)2](ClO4)2, (I), confirms the structure previously reported [Kucharski et al. (1978a). Aust. J. Chem. 31, 53–56], but models the perchlorate over four sets of atomic sites, rather than using just one set of sites as in the original report. The supra­molecular assembly, not reported previously, takes the form of a complex three-dimensional framework built from C—H⋯O hydrogen bonds. The isotypic nickel(II) analogue, [Ni(C15H12N4)2](ClO4)2, (III), has been refined using the original data set [Wang et al. (2011). Acta Cryst. E67, m78], again using a four-component disorder model for the anion, rather than a two-component model as in the original report, leading to more satisfactory Cl—O distances and O—Cl—O angles.
