Structure and electrical properties of a one-dimensional polymeric silver thiosaccharinate complex with argentophilic interactions.

Among the potential applications of coordination polymers, electrical conductivity ranks high in technological interest. We report the synthesis, crystal structure and spectroscopic analysis of an Ag-thiosaccharinate one-dimensional coordination polymer {systematic name: catena-poly[[[aquatetrakis(μ-1,1-dioxo-1,2-benzisothiazole-3-thiolato-κN:S:S)tetrasilver(I)]-μ-4,4'-(propane-1,3-diyl)dipyridine-κN:N'] dimethyl sulfoxide hemisolvate]}, {[Ag(CHNOS)(CHN)(HO)]·0.5CHOS}, with the 4,4'-(propane-1,3-diyl)dipyridine ligand acting as a spacer.

A polymeric silver thiosaccarinate complex with a two-dimensional triply entangled mesh and argentophilic interactions.

Silver(I) complexes with sulfur-donor ligands have a broad range of pharmacological applications. One of the most important factors for tuning the biological activity is the type of donor atom and the ease of ligand replacement. Silver thiosaccharinates display a wide range of structures from mono- to polynuclear complexes.

An ethanol-solvated centrosymmetric dimer of bismuth(III) and thiosaccharinate resulting from `semicoordination' contacts.

In the title compound, bis(μ-1,1-dioxo-1,2-benzothiazole-3-thiolato)-κ(3)N,S:S;κ(3)S:N,S-bis[(1,1-dioxo-1,2-benzothiazole-3-thiolato-κ(2)N,S)(ethanol-κO)bismuth(III)] ethanol hemisolvate, [Bi2(C7H4NO2S2)6(C2H5OH)2]·0.5C2H5OH, three independent thiosaccharinate (tsac) anions chelate the metal centre through the endocyclic N and exocyclic S atoms. The complex also presnts two `semicoordination' contacts, one from a pendant ethanol solvent molecule and a second one from an S atom of a centrosymmetrically related molecule.

A triclinic polymorph of cyclo-tetra-μ-thiosaccharinato-κ8S:S-tetrakis[(triphenylphosphane-κP)silver(I)].

The triclinic structure of the title compound, cyclo-tetrakis(μ-1,1-dioxo-1λ(6),2-benzothiazole-3-thiolato-κ(2)S:S)tetrakis[(triphenylphosphane-κP)silver(I)], [Ag(4)(C(7)H(4)NO(2)S(2))(4)(C(18)H(15)P)(4)], is a polymorph of the previously reported monoclinic structure [Dennehy, Mandolesi, Quinzani & Jennings (2007).

The conformations of two copper(I) complexes of 1H-benzimidazole-2(3H)-thione and thiosaccharinate.

(Acetonitrile-1κN)[μ-1H-benzimidazole-2(3H)-thione-1:2κ(2)S:S][1H-benzimidazole-2(3H)-thione-2κS]bis(μ-1,1-dioxo-1λ(6),2-benzothiazole-3-thiolato)-1:2κ(2)S(3):N;1:2κ(2)S(3):S(3)-dicopper(I)(Cu-Cu), [Cu(2)(C(7)H(4)NO(2)S(2))(2)(C(7)H(6)N(2)S)(2)(CH(3)CN)] or [Cu(2)(tsac)(2)(Sbim)(2)(CH(3)CN)] [tsac is thiosaccharinate and Sbim is 1H-benzimidazole-2(3H)-thione], (I), is a new copper(I) compound that consists of a triply bridged dinuclear Cu-Cu unit. In the complex molecule, two tsac anions and one neutral Sbim ligand bind the metals. One anion bridges via the endocyclic N and exocyclic S atoms (μ-S:N).

Reactive dyes remotion by porous TiO2-chitosan materials.

In this work, the aim was to evaluate the remotion (adsorption plus degradation) of two reactive dyes, Methylene Blue (MB) and Benzopurpurin (BP), from aqueous solutions by the utilization of TiO2-chitosan microporous materials. Two different TiO2-chitosan hybrid materials were synthesized: TiO2-Chit A with 280 mg chitosan/gTiO2 and TiO2-Chit B with 46.76 mg chitosan/g TiO2.

Poly[(mu3-1,1-dioxo-1,2-benzoisothiazole-3-thiolato-kappa3N:S3:S3)silver(I)].

The centrosymmetric title compound, [Ag(C(7)H(4)NO(2)S(2))]n, consists of dinuclear units in which two thiosaccharinate anions each bridge two Ag atoms via an endocyclic N atom and an exocyclic S atom across a crystallographic centre of inversion midway between the Ag atoms. The dimeric units are connected via Ag-S(exo) interactions to create two-dimensional networks. The thiosaccharinate anions bridge in a mu3-S:S:N manner.
