When the dinuclear RuII,II precursor [Ru2(OOCCH3)4] is employed under redox-inert conditions, a RuII,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 RuII,II-HKUST-1 exceeds that of the parent compound HKUST1 (1049 m2/ mmol).
