A zigzag chain structure of a 3-thiapentane-1,5-dithiolato vanadium complex linked by lithium ions

Density functional theory based first-principles core-electron spectroscopic studies on iron-based superconducting 112 materials are presented. The existence of an extra As zigzag chain structure along with Fe–As planes in 112 materials is emphasised. Doping on an As site belonging to a chain by Sb is found to enhance the superconducting transition temperature. This is also shown from calculations with enhanced density of states when doped on chain-As. Therefore, As site identification in 112 is crucial. Theoretically computed As K-edge absorption spectra of two different types of As atoms for Ca0.85La0.15FeAs2 show a distinctly different nature. The sensitivities of As K-edge absorption spectra in the presence and absence of the `core-hole effect' are presented for future possible identification of the same experimentally. In both cases absorption spectra contain several features, the origins of which are thoroughly described in terms of site projected density of states results.

The title compound, Na+·C5H11O8S−[systematic name: sodium (1S,2S,3S,4R)-1,2,3,4,5-pentahydroxypentane-1-sulfonate], is formed by reaction of D-lyxose with sodium bisulfite (sodium hydrogen sulfite) in water. The anion has an open-chain structure in which one of the oxygen atoms of the sulfonate residue, the S atom, the C atoms of the sugar chain and the O atom of the hydroxymethyl group form an essentially planar zigzag chain with the corresponding torsion angles lying between 179.80 (11) and 167.74 (14)°. A three-dimensional bonding network exists in the crystal structure involving hexacoordination of sodium ions by O atoms, three of which are provided by a single D-lyxose–sulfonate unit and the other three by two sulfonate groups and one hydroxymethyl group, each from separate units of the adduct. Extensive intermolecular O—H...O hydrogen bonding supplements this bonding network.

An organic–inorganic hybrid compound,catena-poly[bis(3H-imidazol-1-ium) [[tetracyanido-κ4C-cobalt(III)]-μ-cyanido-κ2C:N-[diaqualithium(I)]-μ-cyanido-κ2N:C]], {(C3H5N2)2[CoLi(CN)6(H2O)2]}n, was synthesized by the reaction of Li3[Co(CN)6] with imidazolium chloride in aqueous solution. The compound crystallizes in the monoclinic space groupC2/c(data collected at 273 K). In the crystal structure, neighbouring [Co(CN)6]3−anionic units are linked by Li+cations through the cyanide groups in atransmode, forming a one-dimensional zigzag chain structure extending along thecaxis. A three-dimensional supramolecular network is formed through hydrogen-bonding interactions and is further stabilized by weak CN...π interactions between the cyanide groups and the imidazolium cations.

In this work, we studied a few surfaces, of which the structures have not yet been revealed, using reflection high-energy positron diffraction (RHEPD). We studied the Ge(111)/Pb and Ge(111)/Sn surfaces that exhibit the phase transition from 3×3 to √3×√3 periodicities at around 200K. We found that in both phases the equilibrium positions of Pb and Sn adatoms are conserved. That is, in the unit-cell, one of three adatoms is located upper position and two of them are located lower positions (one-up-two-down). The phase transition is interpreted in terms of an order-disorder type. We furthermore studied the quasi-one dimensional Si(111)/In surface which exhibits the metal-insulator transition at around 120K. The high temperature phase is well explained as the zigzag chain structure. We found that a dynamic atomic displacement which leads to the formation of hexagon structure occur below 120 K. We confirmed the appearance of the band gap using the surface structure determined from the RHEPD rocking curves.

Single-crystal X-ray analysis reveals that the complex is a one-dimensional zigzag chain structure, and the CdIIcation has a distorted octahedral coordination geometry formed by five N atoms from three different sulfaquinoxaline ligands and one O atom from a water molecule. The fluorescence spectrum reveals that the complex emits strong blue fluorescence and thermal analysis shows that the complex has high thermal stability.

In the title coordination polymer, [Co(C8H4O4)(C12H9N3)] n , the CoII atom exists in an octahedral coordination environment formed by four carboxylate O atoms from two benzene-1,4-dicarboxylate ligands, and two N atoms from the 2-(2-pyridyl)benzimidazole ligand. Bridging by the benzene-1,4-dicarboxylate ligand leads to a zigzag chain structure, and intermolecular N—H...O hydrogen bonds as well as π–π interactions between the pyridyl ring and the benzene ring of the 2-(2-pyridyl)benzimidazole ligand (centroid–centroid distances = 3.678 and 3.697 Å) link the chains into a three-dimensional framework.
