A family of planar disc‐like hexa‐, octa‐ and decametallic Ni II complexes exhibit dominant ferromagnetic exchange. The deca‐ and octametallic clusters [Ni II 10 (tmp) 2 (N 3 ) 8 (acac) 6 (MeOH) 6 ] ( 1 , H 3 tmp=1,1,1‐tris(hydroxymethyl)propane; acac=acetylacetonate) and [Ni II 8 (thme) 2 (O 2 CPh) 4 (Cl) 6 (MeCN) 6 (H 2 O) 2 ] ( 2 , H 3 thme=1,1,1‐tris(hydroxymethyl)ethane) represent rare examples of Ni II ‐based single‐molecule magnets, and [Ni II 10 ] ( 1 ) possesses the largest barrier to magnetisation reversal of any Ni II single‐molecule magnet to date.
