Abstract
The synthesis, crystal structure, magnetic and calorimetric studies of a new clathrate compound of the Hofmann‐type spin crossover (SCO) metal‐organic framework (MOF) {Fe(bpb)[M II (CN) 4 ]} · x Guest (bpb = bis(4‐pyridyl)butadiyne, and M II = Ni, Pt) with characteristic fsc topology is reported. The framework {Fe(bpb)[M II (CN) 4 ]} can host up to 1.5 guest molecules of (trifluoromethyl)benzene and display complete one‐step cooperative SCO behavior. Our systematic study on {Fe(bpb)[Pt(CN) 4 ]} · x Guest shows a general reciprocal correlation between the SCO temperature with the volume of the guest molecules.
