摘要：

(PbS)1.18(TiS2)2 is a misfit layer compound in which two types of slabs, PbS and 2(TiS2), alternate along the c direction. The \TiS2\ blocks (about 11.39 angstrom thick) are interleaved by \PbS\ layers, thus leading to a value for c of 17.46 angstrom. The misfit between the two slab types occurs along the a direction; the parameter values being a(PbS)=5.761 angstrom and a(TiS2) = 3.390 angstrom respectively. This yields a ratio of approximately 1.699, which is irrational but close to 5/3. The common in-plane b parameter is equal to 5.873 angstrom. The PbS unit consists of a {001} slice (half an edge thick) of an NaCl-type f.c.c. cell.
