A 3D Zn(II) coordination polymer with a new semi-rigid tripodal ligand tecton showing 4-connected three-fold interpenetrating diamond network and helical character

A new zinc coordination polymer [Zn(L)(2)](n) (1) (HL = 4'-(4-carboxy-methoxyphenyl)-4,2':6',4 ''-terpyridine) was constructed under hydrothermal condition. X-ray single diffraction studies reveal that 1 shows a three-fold interpenetrating 3D framework with a 4-connected dia topological net, which contains the same number of left- and right-handed 2(1) helical chains. Additionally, photoluminescence property of 1 has been investigated. (c) 2013 Elsevier B.V. All rights reserved.
