Abstract

Abstract : A rare three-coordinated zinc cluster–organic framework was constructed by two types of secondary building units and two polycarboxylate ligands. Abstract : A rare chiral 3D cluster–organic framework {[Zn17 O5 (NTB)6 (NDB)3 ]·41H2 O} n (1 ) (H3 NTB = 4, 4′, 4′′-nitrilotrisbenzoic acid and H2 NDB = 4, 4′-nitrilodibenzoic acid) was prepared and structurally characterized. Complex 1 contains two types of [Zn4 (μ4 -O)(COO)6 ] and unreported [Zn9 (μ3 -O)3 (COO)12 ] SBUs, which link bi- and tri-carboxylic acids and extend to an unprecedented (3, 6, 12)-connected framework. In addition, electronic structure calculations were performed to scrutinize the features of embedded clusters.
