Abstract

Two structurally new Lindqvist hexaniobate-templated silver thiolate clusters, [Nb₆O₁₉@Ag₄₅(ⁱPrS)₂₃(CH₃COO)₁₄] (Ag₄₅) and (H₃O)₄[Nb₆O₁₉@Ag₄₁KS_2.5O₂(H₂O)_7.5(ⁱPrS)₂₄(CH₃COO)₅] (Ag₄₁), were synthesized using a facile one-pot solvothermal approach. Single crystal X-ray diffraction analyses revealed the presence of a classical Lindqvist-type [Nb₆O₁₉]^8- anion template, with ⁱPrS^- and CH₃COO^- surface-protecting ligands in both silver clusters, which can further form two-dimensional Ag₄₅ assembly and one-dimensional Ag₄₁ chain packing structures. Both Ag₄₅ and Ag₄₁ clusters exhibited intriguing photothermal conversion properties and temperature-dependent emission behavior.
