Covalently bonded infinite zigzag chain structure in a novel Zn(II) complex of 2.5-dihydroxy-1.6-benzenedicarboxylic acid

Résumé

Reaction of the disodium salt of 2,5-dihydroxy-1,6-benzenedicarboxylic acid (DHBDC) and zinc sulfate in aqueous solution at room temperature yields complex [Zn(H2O)2(DHBDC)]n. The coordination tetrahedron around Zn center exhibits a highly irregular geometry, two carboxylato oxygen atom and two water–ligand oxygen atoms occupying the coordination sites. Structural analyses of this complex reveal that the individual zero-dimensional units (0D) are covalently linked through their metal ends, forming infinite 1D zigzag chains. These chains, in turn, are engaged in 2D hydrogen bonding, resulting in a 3D supramolecular architecture.
