• The guest-host interaction is one of the promising tools to control the material state. Here, we found that a cyano-bridged compound Na 0.50 Co [ Fe ( C N ) 6 ] 0.72 3.8 H 2 O shows a first-order structural phase transition below a critical pressure P c ( 150 Pa ) at 300 K . Judging from suppression of the OH stretching mode in the infrared spectra, we ascribed the phase transition to desorption of the ligand waters. The phase transition accompanies a significant change of the visible absorption spectra, reflecting the strong hybridization between the Co e g state and the C N σ states.
