[Ni(phen)3]2Sb18S29: A Novel Three-Dimensional Framework Thioantimonate(III) Templated by [Ni(phen)3] Complexes

A novel thioantimonate­(III), namely, [Ni­(phen)3]2Sb18S29 (1; phen = 1,10-phenanthroline), has been solvothermally synthesized. Its structure features a three-dimensional framework with the largest channels in thioantimonates. The chiral [Ni­(phen)3]2+ cations and the Sb:S ratio (1:1.611) in 1 are unique among those in the reported thioantimonates. The thermal stability, optical properties, and electric conductivity as well as the theoretical band structure and density of state of 1 have also been studied.
