The first polyoxometalate based on Keggin dodecatungstoselenate framework supported copper(I) coordination group: [Cu2(2,2′-bpy)4Cl][Cu(2,2′-bpy)2SeW12O40] · 2H2O

The first example of organic–inorganic hybrid polyoxometalate based on Keggin dodecatungstoselenate polyoxoanion, formulated [Cu2(2,2′-bpy)4Cl][Cu(2,2′-bpy)2SeW12O40] · 2H2O (2,2′-bpy=2,2′-bipyridine) (1) has been synthesized hydrothermally and characterized by elemental analyses, IR, XPS, TG and X-ray single crystal diffraction. The structural analysis of 1 shows that the polyoxoanion consists of a Keggin-type dodecatungstoselenate anion [SeW12O40]2− supporting a copper complex group [Cu(2,2′-bpy)2]+.
