Abstract

A new hetero-metal 2-dimensional (2D) spin-crossover complex, {[FeII(3-Fpy)2][AuI(CN)2]2}n (3-Fpy = 3-fluoropyridine) has been synthesized and characterized crystallographically and magnetically. The complex consists of an octahedral FeII ion and a mononuclear [AuI(CN)2]− unit with a linear coordination geometry which combine to form an infinite 2D structure. The spin transition observed for this complex is accompanied by a drastic and reversible change of color from blue to purple.
