Abstract

Four iron(II) complexes [Fe(H2Bpz2)2(L)] (pz = pyrazolyl; L = dppz, or another annelated bipyridyl chelate) crystallize in different molecular stacking motifs through interdigitation of the bipyridyl ligands, often with intercalated toluene or additional uncoordinated bipyridyl. Despite these strong intermolecular interactions the compounds exhibit rather gradual thermal spin-equilibria, because most of the structural rearrangement during spin-crossover occurs at the periphery of the stacks where the crystal packing is less dense.
