Abstract

A new mixed-valence thioarsenate(II,III) [Ni(dap)₃]₄-[As₁₀Cu₂S₁₈] (1, dap = diaminopropane) has been solvothermally synthesized and structurally characterized. 1 features a new heterometallic thioarsenate [As₁₀Cu₂S₁₈]⁸⁻ with mixed valence As²⁺/As³⁺ ions, which is constructed by combination of the chair-shaped tetramer cyclo-[As₄S₈] and the rare heterometallic cluster [As₃CuS₆]. 1 is the first example of transition metal ions encapsulated within mixed-valent thioarsenates(II,III). The optical properties of 1 have also been investigated.
