文摘
Two new metal thiophosphate anions, [Co(Co(P3S8)2)2]4− and [Cr(P3S9)2]3−, have been isolated as single crystals of EMIM (1-ethyl-3-methylimidazolium) salts from ionothermal reaction of the elements in [EMIM][CF3SO3]. The former compound is structurally unique from known thiophosphate anions, contains three cobalt ions in two different coordination environments and oxidation states, and has bridging, polydentate P3S83− groups that coordinate to the cobalt ions through both S and P ions. The chromium thiophosphate anion contains octahedrally-coordinated Cr ions and is structurally similar to the known ion [Ni(P3S9)2]4−. The structures of both salts were determined by single-crystal X-ray diffraction. Both compounds were characterized by EDX and IR spectroscopies.
