Reversible dehydration of complex 1 switches the spin state of cobalt from low‐spin (LS) Co III to high‐spin (HS) Co II (see picture) and allows the magnetic moment to be varied from 0.48 μ B at 120 °C to 4.15 μ B at 220 °C in fully dehydrated complex 1‐220 . notpH 6 =1,4,7‐triazacyclononane‐1,4,7‐triyl‐tris(methylenephosphonic acid).
