mixed-valence transition metal thiophosphates: aunb4p2s20

2003 Structure Structure D 2000 Mixed-Valence Transition Metal Thiophosphates: AuNb 4 P 2 S 20 . — The title compound is synthesized by solid state reaction of the elements (900 °C, 2 weeks). AuNb4P2S20 crystallizes in the monoclinic space group C2/c with Z = 4, as revealed by single crystal XRD. The structure contains infinite chains built by [Nb2S12] and [PS4] units. Au atoms are located within the van der Waals gap of S stoms between infinite chains. Magnetic measurements suggest that the title compound is an antiferromagnetic material with a transition temperature of 45 K. — (KIM*, S.-J.; YIM, S.; GOH, E.-Y.; KANG, H.; KANG, W.; JUNG, D.; Chem.
