Synthesis and characterization of a zinc metal–organic framework with chiral nano-pores

Abstract

Zn₃(BPDC)₂(O₂CH)₂·2Et₂NCHO is a new metal–organic framework with 2,2′-bipyridine-5,5′-dicarboxylate (BPDC) groups as linkers. Although synthesized solvothermally from achiral components, this MOF has a three dimensional (3D) structure with chiral nano-pores. The zinc centers are linked together by carboxylate groups into trinuclear chains; the two terminal zinc atoms are also bound to bipyridine groups.
