The title dinuclear platinum(III) complex, [Pt2(C11H2N)2(C5H4NS)4], forms two crystal structures, viz. the non-solvated and acetonitrile-solvated (C2H3N) forms. For both forms, two (2-pyridylphenyl)platinum units are bridged by two pyridine-2-thiolate (pyt) anions in a head-to-tail configuration, and the other two pyridine-2-thiolate anions occupy the axial position, coordinated through their S atoms. The most remarkable difference between the two forms is the orientation of the axial monodentate ligands. Those for the solvated form are located over the 2-pyridylphenyl ligands, being related by a twofold axis which lies through the centre of the Pt—Pt bond, while the axial pyt ligands for the non-solvated form are oriented irregularly, which is attributable to the dimeric arrangement in the crystal.

A novel Pt(II)–diimine complex exhibits an interesting vapochromic shape‐memory behavior. The amorphous form is converted to a red luminescent vapor‐adsorbed form in the presence of alcoholic vapors. The vapor‐adsorbed form can release the vapors without collapse of the porous structure; this enables it to adsorb other vapors. The vapor‐free porous form can easily be converted to the initial amorphous form by manual grinding. These transformations enable the design of a new chemical sensor with vapor history and ON–OFF switching functions. More information can be found in the Full Paper by A. Kobayashi, M. Kato et al. on page 2682 ff. [ABSTRACT FROM AUTHOR]
