Heterometal–organic framework with pcu net constructed from mixed linear ligands

Abstract

Under the cooperation of two linear organic ligands, a novel heterometal–organic framework [La₂Cu₂(ox)₂L₆]·4HL (HL = 4-pyridin-4-ylbenzoic acid) with non-interpenetrated 3D pcu net was obtained. Notably, the neutral molecular HL species are observed as structure-directing agents, which in turn contribute to the stability of the framework.
