Tr-topic pyridine bis-hydrazone ligands produce polynuclear complexes with Fe(II) and Fe(III) salts with varying nuclearity and metal ion oxidation states. Mononuclear, tetranuclear, hexanuclear, and nonanuclear examples are discussed using structural, magnetic and Mossbauer data. In one case, although X-ray data suggest a [3 x 3] Fe-9 grid (space group P4(2)/n), careful examination of the structure, in conjunction with magnetic and Mossbauer data, indicates an unusual situation where the corner and center sites are present at unit occupancy, whereas side site occupancy is similar to 0.6.
