When the dinuclear Ru-II,Ru-II precursor [Ru-2(OOCCH3)(4)] is employed under redox-inert conditions, a Ru-II,Ru-II analogue of HKUST-1 was successfully prepared and characterized as a phase -pure microcrystalline powder. X-ray absorption near -edge spectroscopy confirms the oxidation state of the Ru centers of the paddle-wheel nodes in the framework. The porosity of 1371 m2/mmol of Ru-II,Ru-II-HKUST-1 exceeds that of the parent compound HKUST1 (1049 m(2)/ mmol).
