Syntheses, structure, topological analysis and luminescent property of a new 3D Zn(II) coordination polymer based on a flexible tetracarboxylate ligand tecton

A new three-dimensional (3D) coordination polymer [Zn(L)(0.5)(DMA)](n) (1), [H4L = 5,5'-(p-xylylenediamino)-1,1',3,3'-(benzene-tetra-carboxylic acid)], was constructed under hydrothermal condition. Single crystal X-ray diffraction indicates that compound 1 shows a (4,4)-connected PtS net with the point (Schlafli) symbol of {4(2) . 8(4)} which contains unusual meso-helical chains. Additionally, photoluminescence property and thermal stability of 1 were investigated. (C) 2014 Elsevier B.V. All rights reserved.
