1.  La2Pb(SiS4)2  
The title structure is occupationally disordered on the La and Pb sites. A large gap was found around the coordination polyhedra, which makes the compound a prospective material in crystal engineering.
Crystals of La2Pb(SiS4)2, dilanthanum(III) lead(II) bis­[tetra­sulfido­sili­cate(IV)], were obtained from the La–Pb–Si–S system and structurally characterized using X-ray single-crystal diffraction. The La and Pb atoms are coordinated in bicapped trigonal prisms of S atoms, with the Si atoms in tetra­hedra. An occupational disorder of the La and Pb centres was refined for one position in the structure. The bicapped trigonal prisms and tetra­hedra share edges. A gap located 2.629 (1) Å from the sulfide anions was found around the coordination polyhedra, which makes La2Pb(SiS4)2 a prospective material in crystal engineering. The Si and one S atom lie on a threefold axis.
