Die reversible Dehydratisierung von Komplex 1 schaltet den Spinzustand des Cobalts von Low‐Spin(LS)‐Co III zu High‐Spin(HS)‐Co II (siehe Bild). Dies ermöglicht es, das magnetische Moment von 0.48 μ B bei 120 °C auf 4.15 μ B bei 220 °C im vollständig dehydratisierten Komplex 1‐220 hochzufahren. notpH 6 =1,4,7‐Triazacyclononan‐1,4,7‐triyltris(methylenphosphonsäure).
