Syntheses, crystal structures and photocatalytic properties of four hybrid iodoargentates with zero- and two-dimensional structures

Abstract

Four new hybrid iodoargentates have been solvothermally prepared and structurally characterized. The title compounds possess semiconductor characterizations and efficient photocatalytic activities under visible light irradiation.

Bromo‐ and Polybromoantimonates(V): Structural and Theoretical Studies of Hybrid Halogen‐Rich Halometalate Frameworks

“…Halide complexeso fp ost-transition (in particular,P b, Sb, and Bi)a nd late transition (Cu, Ag) elements have revealed a number of interesting physicalp roperties relevant for materials science, such as:f erroelectricity and ferroelasticity, [1][2][3] photocatalytic properties, [4][5][6] unusuals olvent-induced color changes, [7] photochromism, [8] thermochromism, [9][10][11] etc. From the point of view of coordination chemistry,a na ttractive feature of these compounds is the great variety of structural types.…”

A Series of Iodoargentates Directed by Solvated Metal Cations Featuring Uptake and Photocatalytic Degradation of Organic Dye Pollutants

“…Fe 3+ ions are solvated with six DMSO molecules, forming [Fe(DMSO) 6 ] 3+ cations to act as counterions for the anionic iodometallate chains. As far as we know, iodoargentates directed by solvated Fe III cations have never been reported, in spite of some published works on iodoargentates templated by [Fe(2,2′‐bipy) 3 ] 3+ or [Fe(1,10‐phen) 3 ] 3+ complex . As shown in Figure d, the neighboring [Ag 6 I 9 ] 3− polyanion chains are stacked together and shape the infinite channels, wherein [Fe(DMSO) 6 ] 3+ cations occupy the void of structure.…”

Non-covalent interaction like electrostatic force amongt hem contributes to the construction and stabilization of the 3D supermolecule.…”

Supramolecular Diiodine-Bromostannate(IV) Complexes: Narrow Bandgap Semiconductors

“…Metal halide complexes, or halometalates, represent the class of coordination compounds which, apart from fundamental interest (in particular, related to structural chemistry), attracts attention due to numerous areas of materials science where they can be applied. Those include design of ferroelectric and ferroelastic materials [1][2][3][4][5], photocatalysis [6][7][8], luminescence [9][10][11][12][13][14][15], photochromism [16,17], etc. However, the most prominent area is photovoltaics.…”
