The centrosymmetric formula unit of the title one-dimensional coordination polymer, [Mn(C7H3N2O6)2(C10H8N2)] n , which is twice the asymmetric unit, contains two MnII ions, four 3,5-dinitrobenzoate anions and two 2,2′-bipyridine ligands. The 3,5-dinitrobenzoate anions connect the MnII atoms through their O atoms, resulting in the formation of a one-dimensional chain structure.

Self-assembly of metal–organic coordination polymers occurs because of enthalpically favorable interactions. In the case of the bulky 4,4′-(anthracene-9,10-diyl)dibenzoic acid ligand (abdH2), we demonstrate that the presence of numerous π–π and C—H...π interactions outweigh the formation of saturated coordination complexes with zinc, leading to the formation of a dimethylformamide (DMF) solvate, namely 4,4′-(anthracene-9,10-diyl)dibenzoic acid dimethylformamide disolvate, C28H18O4·2C3H7NO or [(abdH2)(DMF)2], at low concentrations of zinc. Meanwhile, at higher zinc concentrations, the abdH2 ligand gives rise to the nonporous one-dimensional coordination polymer catena-poly[[bis(dimethylformamide-κO)zinc(II)]-μ-4,4′-(anthracene-9,10-diyl)dibenzoato-κ2 O:O′], [Zn(C28H16O4)(C3H7NO)2] n or [Zn(abd)(DMF)2] n , when assembled in dimethylformamide, while a related compound is observed when N,N-dimethylacetamide (DMA) is used as the solvent, namely catena-poly[[[bis(N,N-dimethylacetamide-κO)zinc(II)]-μ-4,4′-(anthracene-9,10-diyl)dibenzoato-κ2 O:O′] N,N-dimethylacetamide monosolvate], {[Zn(C28H16O4)(C4H9NO)2]·C4H9NO} n or {[Zn(abd)(DMA)2]·DMA} n . Attempts to use other amide-based solvents did not give rise to any other assembled structures.

The azide anion is a short bridging ligand that has been used extensively to construct magnetic coordination polymers, and fundamental magneto-structural correlations have been substantiated by theoretical calculations. The copper(II) coordination polymer poly[bis(μ-azido-κ2N1:N1)(μ4-homophthalato-κ4O:O′:O′′:O′′′)bis(pyridine-κN)dicopper(II)], [Cu2(C9H6O4)(N3)2(C5H5N)2]n, was synthesized from homophthalic acid (2-carboxyphenylacetic acid), pyridine and azide (N3−) by a hydrothermal reaction. Single-crystal structure analysis indicated that it features a one-dimensional chain structure which is comprised of (μ1,1-N3−)(μ-syn–syn-COO−)2- and (μ1,1-N3−)2-bridged tetranuclear CuIIunits. Magnetic measurements revealed that the compound exhibits dominant antiferromagnetic behaviour.

Spherical neodymium–iron–boron magnets are permanent magnets that can be assembled into a variety of structures owing to their high magnetic strength. A one-dimensional chain of these magnets responds to mechanical loadings in a manner reminiscent of an elastic rod. We investigate the macroscopic mechanical properties of assemblies of ferromagnetic spheres by considering chains, rings and chiral cylinders of magnets. Based on energy estimates and simple experiments, we introduce an effective magnetic bending stiffness for a chain of magnets and show that, used in conjunction with classic results for elastic rods, it provides excellent estimates for the buckling and vibration dynamics of magnetic chains. We then use this estimate to understand the dynamic self-assembly of a cylinder from an initially straight chain of magnets.
