- Heriot-Watt University, Department of Chemistry, Edinburgh EH14 4AS (United Kingdom)
A new organically templated indium selenide, [C{sub 6}H{sub 16}N{sub 2}][In{sub 2}Se{sub 3}(Se{sub 2})], has been prepared hydrothermally from the reaction of indium, selenium and trans-1,4-diaminocyclohexane in water at 170 deg. C. This material was characterised by single-crystal and powder X-ray diffraction, thermogravimetric analysis, UV-vis diffuse reflectance spectroscopy, FT-IR and elemental analysis. The compound crystallises in the monoclinic space group C2/c (a=12.0221(16) A, b=11.2498(15) A, c=12.8470(17) A, {beta}=110.514(6){sup o}). The crystal structure of [C{sub 6}H{sub 16}N{sub 2}][In{sub 2}Se{sub 3}(Se{sub 2})] contains anionic chains of stoichiometry [In{sub 2}Se{sub 3}(Se{sub 2})]{sup 2-}, which are aligned parallel to the [1 0 1] direction, and separated by diprotonated trans-1,4-diaminocyclohexane cations. The [In{sub 2}Se{sub 3}(Se{sub 2})]{sup 2-} chains, which consist of alternating four-membered [In{sub 2}Se{sub 2}] and five-membered [In{sub 2}Se{sub 3}] rings, contain perselenide (Se{sub 2}){sup 2-} units. UV-vis diffuse reflectance spectroscopy indicates that [C{sub 6}H{sub 16}N{sub 2}][In{sub 2}Se{sub 3}(Se{sub 2})] has a band gap of 2.23(1) eV. - Graphical abstract: [C{sub 6}H{sub 16}N{sub 2}][In{sub 2}Se{sub 3}(Se{sub 2})], prepared under hydrothermal conditions, contains one-dimensional chains of stoichiometry [In{sub 2}Se{sub 3}(Se{sub 2})]{sup 2-}, in which four-membered [In{sub 2}Se{sub 2}] and five-membered [In{sub 2}Se{sub 3}] rings alternate. Highlights: > New one-dimensional indium selenide prepared under hydrothermal conditions. > The [In{sub 2}Se{sub 3}(Se{sub 2})]{sup 2-} chains are a new structural motif for Group 13 chalcogenides. > Unusual presence of (Se{sub 2}){sup 2-} moieties. > Optical band gap of 2.23(1) eV.
