A New Microporous Hydrogen-Bonding Framework Constructed from 1-(4-Hydroxyphenyl)-5-Thioacetatetetrazole

Abstract

The new complex with flexible heterocyclic carboxylate ligand, [Ba(HL−)2(H2O)3]·H2O (H2L = 1-(4-Hydroxyphenyl)-5-thioacetatetetrazole), were synthesized and structurally determined by X-ray diffraction analysis. The complex belongs to the monoclinic system, space group C2/c. The center Ba(II) is nine-coordinated by six carboxylate oxygen atoms from four HL-ligands and three water molecules in a distorted monocapped square trans-prism geometry. The ligand serves as a bridge to link two adjacent Ba(II) atoms into a chain structure which are further assembled into the final three-dimensional supramolecular architecture with microporous open channel via hydrogen bonds. A new complex is assembled into three-dimensional supramolecular architecture with microporous open channel via hydrogen bonds.
