The initial employment of cyanato groups in higher oxidation state manganese cluster chemistry, in conjunction with the gem‐diolate form of di‐2‐pyridylketone or 2,6‐diacetylpyridine dioxime chelate ligands, has afforded structurally interesting Mn II/III 14 and Mn II/III/IV 16 clusters, respectively. In both complexes, the end‐on bridging cyanato groups show an obvious preference in binding through their O atom, a significantly different ligation than that for the homoatomic‐type N 3 – ligand. The Mn 14 compound shows entirely visible out‐of‐phase signals below 5 K and large hysteresis loops below 2 K.
