Abstract
<jats:title>Abstract</jats:title><jats:p>The novel uranium thiophosphate CsLiU(PS<jats:sub>4</jats:sub>)<jats:sub>2</jats:sub>has been synthesized by reacting uranium metal, Cs<jats:sub>2</jats:sub>S, Li<jats:sub>2</jats:sub>S, S, and P<jats:sub>2</jats:sub>S<jats:sub>5</jats:sub>at 700 °C in an evacuated silica tube. The crystal structure was determined by single‐crystal X‐ray diffraction techniques. CsLiU(PS<jats:sub>4</jats:sub>)<jats:sub>2</jats:sub>crystallizes in the rhombohedral space group<jats:italic>R</jats:italic><jats:styled-content>$\bar{3}$<jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="graphic/tex2gif-ueqn-1.gif" xlink:title="equation image" /></jats:styled-content><jats:italic>c</jats:italic>(<jats:italic>a</jats:italic>= 15.2797(7) Å;<jats:italic>c</jats:italic>= 28.778(2) Å,<jats:italic>V</jats:italic>= 5818.7(5) Å<jats:sup>3</jats:sup>,<jats:italic>Z</jats:italic>= 18). The structure ofCsLiU(PS<jats:sub>4</jats:sub>)<jats:sub>2</jats:sub>is a unique three‐dimensional U(PS<jats:sub>4</jats:sub>)<jats:sub>2</jats:sub><jats:sup>2–</jats:sup>framework with large tunnels with an approximate diameter of 6.6 Å running parallel to the crystallographic<jats:italic>c</jats:italic>axis. The tunnels are filled with Cs<jats:sup>+</jats:sup>cations. The smaller Li<jats:sup>+</jats:sup>cations are located at tetrahedral sites at the periphery of the channels. In the structure of CsLiU(PS<jats:sub>4</jats:sub>)<jats:sub>2</jats:sub>the uranium atoms are coordinated by thiophosphate groups in a pseudotetrahedral fashion, and the PS<jats:sub>4</jats:sub>groups act as linear connectors. Topologically, CsLiU(PS<jats:sub>4</jats:sub>)<jats:sub>2</jats:sub>may be regarded a chalcogenide analogue of silicate frameworks, with the uranium atoms and PS<jats:sub>4</jats:sub>groups replacing silicon and oxygen atoms. Alternatively, CsLiU(PS<jats:sub>4</jats:sub>)<jats:sub>2</jats:sub>may be viewed as a coordination polymer, which is formed in salt melts by the solid state equivalent of the “self‐assembly” reactions in solution. Magnetic susceptibility measurements indicated Curie–Weiss‐type behavior between 4 K and 300 K. The<jats:italic>μ</jats:italic><jats:sub>eff</jats:sub>of 2.83 μ<jats:sub>B</jats:sub>at 300 K is in agreement with an f<jats:sup>2</jats:sup>configuration of U<jats:sup>4+</jats:sup>.</jats:p>
