Poly[[{μ3-tris­[2-(4-phenyl-1,2,3-triazol-1-yl)eth­yl]amine}silver(I)] hexa­fluorido­phosphate]

The title compound, {[Ag(L)]PF6)n {L is tris­[2-(4-phenyl-1,2,3-triazol-1-yl)eth­yl]amine, C30H30N10}, consists of alternating two-dimensional cationic layers of [Ag(L)]+ and anionic PF6 − layers. Each AgI atom is three coordinated in a T-shaped geometry by three N atoms from three ligands. Each ligand links three AgI atoms, generating a two-dimensional network structure with two different metallacycles, A and B. In A, eight coordination units from four ligands connect four AgI atoms, forming a 48-membered ring. In B, four coordination units from two ligands link two AgI atoms, forming a 24-membered ring. Each B ring is surrounded by four A rings, and each A ring has four A and four B rings as neighbours. This cationic layer thus generates a 4.82 topology network, with each AgI centre and ligand acting as a three-connected topological node

鉄-スズ系複合酸化物のガスセンサ性能と局所構造(B. 生活科学)

The Fe K-edge X-ray absorption spectra have been recorded to study local structures around iron for fine powdery α-Fe_2O_3-SnO_2 gas sensor which was prepared by the thermal decomposition of coprecipitates from aqueous ferric sulfate and stannic chloride solutions at pH 8. Tin atoms are substituted for iron atoms in the corundum structure of α-Fe_2O_3 below 15 mo 1% of SnO_2 which is the limit of dissolution. Further addition of SnO_2 brings about the system unstable by that SnO_2 enters the lattice as a substitutional defect and produces tetrahedral iron oxide species. The high sensor sensitivity for CH_4 is intimately correlated with the amount of dissolved SnO_2 into α-Fe_2O_3
