摘要：
The title compounds (natural low-dimensional semiconductors) show strong excitonic optical absorption bands in the UV-visible spectral region, because of the dielectric confinement of excitons, as in the cases of other similar systems based on PbX(4)(2-), SnX(4)(2-), Pt-I...X-Pt-IV-X, CdxSy-clusters etc.
