In the title cooridnation polymer, {[Cu(C(6)H(2)O(5))(C(3)H(4)N(2))(2)(H(2)O)]·3H(2)O}(n), an infinite chain is formed along [001] by linking of the Cu(C(3)N(2)H(4))(2)(H(2)O) entities with two bridging monodentate carboxyl-ate groups of two different furan-2,5-dicarboxyl-ate dianions. The geometry of the Cu(2+) ion is a square-based pyramid with the water atom in the apical position and the ligand O and N atoms in a trans orientation. The dihedral angle between the imidazole planes is 83.96 (14)°. O(w)-H⋯O and N(i)-H⋯O (w = water and i = imidazole) hydrogen bonds help to establish the packing.

A novel one-dimensional zigzag chain-like Co coordination polymer constructed from 4,4'-bi-pyridine (4,4'-bpy) and 2-hy-droxy-benzoate (2-OHbenz) ligands, namely, -poly[[(4,4'-bi-pyridine-κ)-(μ-2-hy-droxy-benzoato-κ :')(2-hy-droxy-benzoato-κ ,')cobalt(II)]-μ-4,4'-bi-pyridine-κ :'-[aquahemi(μ-4,4'-bi-pyridine-κ :')(2-hy-droxy-benzoato-κ(2-hy-droxy-benzoato-κ :')cobalt(II)], [Co(CHO)(CHN)(HO)] , has been synthesized by reacting cobalt(II) nitrate trihydrate, 4,4'-bpy and 2-hy-droxy-benzoic acid in a mixture of water and methanol at room temperature. There are two independent Co centers, Co1 and Co2, in the asymmetric unit, revealing a distorted octa-hedral geometry with chromophore types of [CoNO] and [CoNOO'], respectively. The Co1 ions are doubly bridged by 2-OHbenz ligands with - coordination mode, generating a dinuclear unit.

A one-dimensional nickel(II) coordination polymer with the mixed ligands 6-fluoro-nicotinate (6-Fnic) and 4,4'-bi-pyridine (4,4'-bpy), namely, -poly[[di-aqua-bis-(6-fluoro-pyridine-3-carboxyl-ato-κ)nickel(II)]-μ-4,4'-bi-pyri-dine-κ :'] trihydrate], {[Ni(6-Fnic)(4,4'-bpy)(HO)]·3HO} , (), was prepared by the reaction of nickel(II) sulfate hepta-hydrate, 6-fluoro-nicotinic acid (CHFNO) and 4,4'-bi-pyridine (CHN) in a mixture of water and ethanol. The nickel(II) ion in is octa-hedrally coordinated by the O atoms of two water mol-ecules, two O atoms from -monodentate 6-fluoro-nicotinate ligands and two N atoms from bridging 4,4'-bi-pyridine ligands, forming a isomer. The bridging 4,4'-bi-pyridine ligands connect symmetry-related nickel(II) ions into infinite one-dimensional polymeric chains running in the [10] direction.

Coordination polymers (CPs) with specific structures and functional luminescence have been widely designed as sensors for detecting small molecules and ions. In this study, with or without the help of an N-donor auxiliary linker, three new Zn CPs, namely, three-dimensional (3D) poly[[pentaaquabis[μ-5-(4-carboxybenzyloxy)isophthalato]bis[μ-5-(4-carboxylatobenzyloxy)isophthalato]di-μ-hydroxido-hexazinc(II)] trihydrate], {[Zn(CHO)(CHO)(OH)(HO)]·3HO} or {[Zn(μ-HL)(μ-L)(μ-OH)(HO)]·3HO}, (I), one-dimensional (1D) catena-poly[[[aqua(1,10-phenanthroline)zinc(II)]-μ-5-(4-carboxybenzyloxy)isophthalato] dihydrate], {[Zn(CHO)(CHN)(HO)]·2HO} or {[Zn(μ-HL)(phen)(HO)]·2HO} (phen is 1,10-phenanthroline), (II), and 3D poly[diaquatetrakis(4,4'-bipyridine)bis[μ-5-(4-carboxylatobenzyloxy)isophthalato]di-μ-formato-di-μ-hydroxido-pentazinc(II)], [Zn(CHO)(HCOO)(OH)(CHN)(HO)] or [Zn(μ-L)(bpy)(μ-OH)(μ-HCOO)(HO)] (bpy is 4,4'-bipyridine), (III), have been constructed from the semi-rigid tricarboxylic acid 5-(4-carboxybenzyloxy)isophthalic acid (HL) under hydrothermal conditions. CP (I) exhibits a twofold interpenetrated 3D+3D→3D skeleton with a 3,5-conn topology constructed from triangular trinuclear [Zn(COO)(μ-OH)] clusters, in which the HL ligand adopts three different coordination modes.

Properties related to the size and shape of Hirshfeld surfaces provide insight into the nature and strength of interactions among the building blocks of molecular crystals. In this work, we demonstrate that functions derived from the curvatures of the surface at a point, namely, shape index (S) and curvedness (C), as well as the distances from the surface to the nearest external (d) and internal (d) nuclei, can be used to help understand metal-ligand interactions in coordination polymers. The crystal structure of catena-poly[[[(1,10-phenanthroline-κN,N')copper(II)]-μ-4-nitrophthalato-κO:O] trihydrate], {[Cu(CHNO)(CHN)]·3HO}, described here for the first time, was used as a prototypical system for our analysis.
