The title compound, [AgCd(NCS)(3)(C(22)H(17)N(3))](n), is a hetero-atom ribbon coordination polymer. The central Cd atom is chelated by the 4'-p-tolyl-2,2':6',2''-terpyridine ligand and is coordinated by the N atoms of three thio-cyanate ions in an octa-hedral geometry whereas the Ag atom is coordinated by the four S atoms of four thio-cyanate ions in a distorted tetra-hedral geometry. Of the t...

In the title coordination polymer, [Cd(C(7)H(4)N(3)O(2))(2)(C(3)H(7)NO)(2)](n), the Cd(II) atom, lying on an inversion center, is six-coordinated in a distorted N(4)O(2) octa-hedral geometry. The N atoms of the 4-nitrophenylcyanamide anions form the equatorial plane and the O atoms of the dimethyl-formamide mol-ecules occupy the axial positions. The anions act as bridging ligands, connecting th...

The coordination compounds of Fe (II) and Fe(III) with phthalic acid were synthesized. The compounds were studied by X-Ray Diffraction (XRD), Differential Thermal Analysis (DTA), and IR spectroscopy. It has been established that, regardless of the oxidative number of iron, the synthesis products have the same chemical composition and chemical formula - [Fe2(o-C6H4...

The title compound, [Sn(C3H7)2(H2O)(C2O4)] n , represents the first diorganotin(IV) oxalate hydrate to be structurally characterized. The tin(IV) atom of the one-dimensional coordination polymer is located on a twofold rotation axis and is coordinated by two chelating oxalate ligands with two slightly different Sn-O bond lengths of 2.290 (2) and 2.365 (2) Å, two symmetry-related n-propyl groups...

Two new structure-related tripodal ligands featuring salicylamide pendant arms, 1,3,5-tris{[(2'-furfurylaminoformyl)phenoxyl]methyl}-2,4,6-trimethylbenzene (L(I)) and 1,1,1-tris{[(2'-furfurylaminoformyl)phenoxyl]methyl}ethane (L(II)) have been designed and synthesized with the ultimate aim of self-assembling lanthanide polymers with interesting luminescent properties. Among two series of Ln(III...

Coordination polymer (CP) formation is an unexplored area in weak-interaction chemistry due to the difficulty of monitoring the coordination process. By using cold-spray ionization mass spectrometry (CSI-MS), several kinds of coordination compounds were detected when CuI metal and the 4,7-phenanthroline organic bridged ligand were mixed in solution. The observed ion peaks could be reasonably ...

Nowadays there is a high demand for specialized functional materials for specific applications in sensors or biomedicine (e.g. fMRI). For their implementation in devices, nanostructuring and integration in a composite matrix are indispensable. Spin crossover complexes are a highly promising family of switchable materials where the switching process can be triggered by various external stimuli. ...

Coordination-polymer materials represent a rapidly growing area in modern chemistry and materials science. These structures can now be made in many forms, including crystalline metal–organic frameworks (MOFs) and welldefined (in terms of size and shape) infinite-coordinationpolymer (ICP) nanoand microparticles. These materials show promise in many applications, including catalysis, gas storage,...

Optically active polymers containing P-stereogenic bisphosphine and 1,2,3-triazole units in the main chain were obtained by copper-catalyzed Huisgen cycloaddition. The repeating unit of the polymer adopted bidentate as well as tetradentate coordination, leading to the change in the conformations of the polymer via complexation with transition metals.

A porous coordination polymer [Cu(3)(btc)(2)] with controllable size and morphology from nanocube to microoctahedron was readily synthesized in an ethanol-water mixture at room temperature by adjusting the concentration of the surfactant and the polymer shows size- and morphology-dependent sorption properties.
