The ethanol vapor adsorption behavior and the inclusion crystal structure of a 1D-transformable coordination polymer host were characterized. The adsorption jump was observed during phase transition or two-phase equilibrium with abnormal adsorption enthalpy caused by the nature of "mass induced phase transition." The included ethanol guests selectively form O-H...O hydrogen bonded pairs inside channels, suggesting selective construction of a specific cluster/aggregate in pores under control of thermodynamic factors and cooperative intermolecular interactions among the guest and channel surface.

The structure of a linear chain complex [Rh(II)2(O2CPh)4(pyz)]∞ was characterized by X-ray diffraction analysis. The solid indicates nitrogen adsorption on a microporous medium although the crystal does not seem to have a microporous structure. There is a high possibility that the structure changes to open the crystal packing for gas molecules.

Sheer magnetism: The phase transitions and magnetic behavior of included oxygen in a single crystal were studied at low temperature. The system exhibits three correlated structural and magnetic phases. The distinct middle‐temperature phase shows a one‐dimensional‐chain arrangement of oxygen trimers with an anomalous magnetization response to external magnetic fields.

Eine denkbar einfache Methode zur Erzeugung von Einkristall‐Clathraten besteht darin, einen Adsorbat‐Einkristall in eine Gasatmosphäre zu bringen (siehe Bild; Rh magenta, O rot, C und H grau, N blau). Dieser Ansatz könnte zur Herstellung einer Vielzahl von niederdimensionalen Aggregatkristallen mit potenziellen Quanteneffekten angewendet werden.

CO2 inklusive: Der reversible Phasenübergang beim Abkühlen des eindimensionalen Koordinationspolymers [Rh2(CO2Ph)4(pyz)]n (pyz=Pyrazin; siehe Bild, links) wird durch Adsorption von CO2 bewirkt. Dabei entsteht eine Einschlussverbindung, die bis zu drei Moleküle CO2 pro Rh2‐Einheit in ihren Kanälen einlagern kann.
