Tuning the Spin State of Cobalt in a Co-La Heterometallic Complex through Controllable Coordination Sphere of La

Reversible dehydration of complex 1 switches the spin state of cobalt from low‐spin (LS) CoIII to high‐spin (HS) CoII (see picture) and allows the magnetic moment to be varied from 0.48 μB at 120 °C to 4.15 μB at 220 °C in fully dehydrated complex 1‐220. notpH6=1,4,7‐triazacyclononane‐1,4,7‐triyl‐tr...
