Abstract: The quaternary thallium thiophosphate TlPbPS₄ (thallium lead phosphorus tetrasulfide) was obtained by reacting elemental Pb with a melt, formed in situ, of Tl₂S, P₂S₅ and S. The crystal structure is composed of parallel zigzag layers, which consist of condensed S₆ distorted trigonal prisms alternately centred by Tl and Pb atoms. The layers are stacked perpendicular to the crystallographic a axis and are joined by [PS₄] tetrahedra. TlPbPS₄ is isostructural with TlEuPS₄ and TlSnPS₄.
