Synthesis for the preparation of multi‐spin systems 5 and 7. a) Scheme for synthesis of 5. a(i) DIPEA, DMF, 75 °C, 16 h. a(ii) CrF3, xs HO2CtBu, nickel carbonate, 160 °C, 24 h. a(iii) DCC, DMAP, THF, 50 °C, 16 h. a(iv) Acetone / pentane. b) Scheme for synthesis of 7. b(i) nPrOH, iso‐nicotinic acid 24 h. b(ii) Acetone / pentane. Insert: Full structure of [Cr7NiF8(O2CBu)16]− (top left) and [Cr7NiF3(Etglu)(O2C t Bu)15(OH2)] (bottom left); the coloured spheres correspond to the different atom types: Cr (green), Ni (lilac), O (red), N (blue), F (yellow), C (silver). Hydrogens omitted for clarity.
