A new type of composite MOFs based on high-valent Sb(v)-based units and cuprous-halide clusters

Abstract

An unusual high-valent Sb(V)-based unit [SbL₂]⁻ (L = 2-(hydroxymethyl)-2-(pyridin-4-yl)-1,3-propanediol) was developed for the first time to combine with various cuprous-halide clusters for the construction of a brand-new class of heterometallic MOFs. This work not only promotes the limited development of Sb-based MOFs, but also provides a practical strategy for developing new types of composite materials.
