Succession along the a13 (a23) axis of the (PbySb1 − yS) Q layers with a distorted PbS-/NaCl-type structure and the [Snx(Cu2)1 − x]S2 H layers with a `CdI2-type' structure. A few unit cells are given along a11 to illustrate the incommensurateness. Broken lines indicate the two subsystem interaction. |
