摘要：

The new lead potassium thiophosphate KPbPS4 was synthesized by reacting Pb with an in situ formed melt of K2S3, P2S5 and S. Its structure was determined by single crystal X-ray diffraction. KPbPS4 crystallizes as yellow crystals in the orthorhombic system, space group Pnma (no. 62), a = 17.045(3) angstrom, b = 6.660(1) angstrom, c = 6.473(1) angstrom, V = 734.9(3) angstrom(3), Z = 4. The structure is isotypic with that of KEuPS4 and consists of two-dimensional [PbPS4](n)(n-) anionic layers extending in the yz plane, separated by alkali cations. The layers are comprised of alternating zigzag parallel chains of PbS6 trigonal prisms running along [010] connected by PS4 tetrahedral units. (c) 2005 Elsevier SAS. All rights reserved.
