title: A chiral interdigitated supramolecular network assembled from single-stranded helical tubes.
abstract: The amino-functionalized helical chiral one-dimensional coordination polymer catena-poly[[bis(pyridine-κN)zinc(II)]-μ-2-aminobenzene-1,4-dicarboxylato-κ(4)O(1),O(1'):O(4),O(4')], [Zn(C(8)H(5)NO(4))(C(5)H(5)N)(2)](n), has an extended structure that is assembled from 2-aminobenzene-1,4-dicarboxylate anions and Zn(2+) cations and which presents a left-handed 4(3) helix with a pitch of 25.6975 (9) Å. All the pyridine rings and all the amino groups point away from the helix to generate a hollow tube with a cross-section of approximately 8 × 8 Å running parallel to the crystallographic c direction. Each single-stranded helix is interdigitated with four neighbouring helices via N-H···O hydrogen bonds, which gives rise to a dense homochiral three-dimensional supramolecular network.
