We synthesized novel “Soma–Iwamoto-type” complexes that contain the 4-methoxypyrimidine ligand. The guest clathrate complexes demonstrate the SCO phenomenon and interesting rarely reported penetrated structures with two Soma–Iwamoto-type stru

57Fe Mössbauer spectroscopic results on the 2D Hofmann-like coordination polymer Fe(4-Clpy)2Ni(CN)4 (sample 1) indicate that iron(II) ions are in a high spin state both at R.T. and T = 80 K, showing that the compound exhibits no spin crossover (SCO)

A Hofmann-type two-step spin-crossover (SCO) complex with a pyrimidine derivative ligand, Fe(4-methylpyrimidine)2[Au(CN)2]2, was synthesized, and this complex shows a two-step SCO phenomenon in the intermediate state. Symmetry breaking also occurs in
