TL;DR: In this article, a dipyridyl spacer 2,5-bis(4-pyride)-1,3,4-oxadiazole (bpo) with pyridine-2,6-dicarboxylic acid (H2pydc) was used to construct a metal-organic supramolecular networks.

TL;DR: In this article, a novel 3d-4f BDC-salamo-based coordination polymeric poly(L)Ni(BDCD)Gd(NO3)(DMF) was presented.
Abstract: A unprecedented hetero-bimetallic 3d-4f BDC-salamo-based coordination polymer, [(L)Ni(BDC)Gd(NO3)(DMF)] was prepared and validated via elemental analyses, IR and UV–Visible absorption spectra, DFT calculation, and X-ray crystallography. The six-coordinated Ni1 ion lies at the N2O2 donor site of the L2− moiety, and one DMF O atom and carboxylate O atom occupy, collectively, the axial positions, and form a twisted octahedron. The nine-coordinated Gd1 ion consists of three oxygen atoms (O12, O13, and O14) of two carboxylate groups, two oxygen atoms (O8 and O9) derived from one bidentate nitrate group, and an O2O2 coordination site (O1, O2, O6, and O5) of the L2− unit, forming a twisted three-capped triangular prism coordination geometry. Compared to the ligand (H2L), the fluorescence intensity decreases due to the coordination of metal ions. Meanwhile, the antibacterial activities are researched.

TL;DR: A mixed-valence Fe(II) /Fe(III) cyanide-bridged coordination polymer, {[Fe(Tp)(CN)3 ]2 Fe(bpe)⋅5 H2 O}n, which demonstrates a thermally induced charge-transfer phase transition, is described.
Abstract: Heterometallic Prussian blue analogues are known to exhibit thermally induced charge transfer, resulting in switching of optical and magnetic properties. However, charge-transfer phase transitions have not been reported for the simplest FeFe cyanide-bridged systems. A mixed-valence Fe(II) /Fe(III) cyanide-bridged coordination polymer, {[Fe(Tp)(CN)3 ]2 Fe(bpe)⋅5 H2 O}n , which demonstrates a thermally induced charge-transfer phase transition, is described. As a result of the charge transfer during this phase transition, the high-spin state of the whole system does not change to a low-spin state. This result is in contrast to FeCo cyanide-bridged systems that exhibit charge-transfer-induced spin transitions.

TL;DR: Ferromagnetic and antiferromagnetic alternating interactions within and between chains, respectively, were interpreted for a one-dimensional coordination polymer having high-spin MnII centers bridged by azido ligands.
Abstract: Ferromagnetic and antiferromagnetic alternating interactions within and between chains, respectively, were interpreted for a one-dimensional coordination polymer having high-spin (S = 5/2) MnII centers bridged by azido ligands, namely, [Mn(bpm)(N3)2]n (bpm = bis(pyrazol-1-yl) methane)
