Abstract

Cobalt(II) compounds [Co(pyterpy)Cl2]·MeOH (1·(MeOH)) and [Co(pyterpy)Cl2]·2H2O (1·(2H2O)) were synthesized. The compound 1·(MeOH) forms the quasi 3-D networks by making π-π stacking between the 1-D chains. The methanol molecules from 1·(MeOH) can be removed by heating, and substituted by absorption of water molecules. The MeOH molecules in 1·(MeOH) are removed by heating at 410 K, and they are substituted by water molecules to form 1·(2H2O). 1·(2H2O) exhibits a S = 3/2 (HS) ⇆ S = 1/2 (LS) spin transition with a thermal hysteresis. We have succeeded in constructing a guest dependent 1-D spin-crossover cobalt(II) compound.
