Synthesis and characterization of bimetallic metal-organic framework Cu-Ru-BTC with HKUST-1 structure

The bimetallic metal-organic framework Cu-Ru-BTC with the stoichiometric formula Cu2.75Ru0.25(BTC)(2)center dot xH(2)O, which is isoreticular to HKUST-1, was successfully prepared in a direct synthesis using mild reaction conditions. The partial substitution of Cu2+ by Ru3+ centers in the paddlewheel structure and the absence of other Ru-containing phases was proven using X-ray absorption spectroscopy.
