Metastable up to 280 K , {Mo V Cu I Cu II 5 } ( S =3) forms as a result of intramolecular electron transfer from the Mo IV center to one of the Cu II termini of the [Mo IV (CN) 2 (CN‐Cu II (L)) 6 ] 8+ complex, ( 1 ; L=tris(2‐aminoethyl)amine) upon light excitation (see picture: Mo yellow; C black; N blue; Cu purple). This process is thermally reversible. Compound 1 shows the magnetic properties of six independent Cu II ions ( S =1/2).
