Room-temperature spin crossover observed for [(TPyA)Fe-II(DBQ(2-))Fe-II(TPyA)](2+) [TPyA = tris(2-pyridylmethyl)amine; DBQ(2-)=2,5-di-tert-butyl-3,6-dihydroxy-1,4-benzoquinonate]
Dinuclear [(TPyA)Fe-II(DBQ(2-))Fe-II(TPyA)](BF4)(2) possesses extensive pi-pi interactions between the Fe-II dimers that give rise to a two-dimensional supramolecular sheet structure. The magnetic susceptibility shows a room-temperature spin-crossover behavior; however, thermal hysteresis is not observed.
