摘要：

The crystal structure of the monoclinic (PbS)1.14(NbS2)2 polytype has been determined. The structure which is analysed in terms of a composite crystal consists of (PbS), 2x(NbS2) and common parts. PbS and (NbS2)2 slabs alternate along the c direction. The misfit between the two types of slabs occurs along the a direction. Some comments about polytypism and die presence of additional Nb atoms within the VdW gap are given.
