(enH2)4.5[In(AsVS4)3][As2III(μ-S2)S3]Cl and (enH2)MnAsIIIAsVS6: two thioarsenates(iii, v) with mixed-valent optical properties†
Abstract
Two mixed-valent thioarsenates, namely (enH2)4.5[In(AsVS4)3][As2III(μ-S2)S3]Cl (1) and (enH2)MnAsIIIAsVS6 (2) (en = ethylenediamine), have been solvothermally synthesized and characterized. Thermal stability, magnetic and mixed-valent optical properties, as well as theoretical band structures and DOSs, of 1 and 2 have also been studied.
