Abstract

A copper-based metal-organic frameworks (Cu(II)-MOF) functionalized with a new linker, a 5-substituted isophthalic acid bearing a propargyl carbamate group was prepared, intended to provide a support for gold species for potential catalytic applications.1 The novel material was fully characterized using several complementary techniques. Synchrotron X-ray diffraction data analysis, in particular, revealed that this MOF, labelled Cu(II)-MOF contains a complex network of 5-substituted isophthalate anions bound to Cu(II) centers, arranged in pairs within paddlewheel fragments, with a short Cu-Cu distance. Quite unexpectedly, the apical atom in the paddlewheel structure belongs to the carbamate carbonyl oxygen atom. Such extra coordination by the propargyl carbamate groups influences the MOF porosity, a feature that was also confirmed by BET measurements.
