Organic/inorganic hybrids of MX chain

We have investigated organic/inorganic hybrids of MX chain in order to make a dynamical mixed-valence system as the first attempt. We have obtained the hybrids of the MX (PtCl, PtBr, PtI) chains with organic sulfonate as a counter ion. They show deep red color for PtCl, greenish golden color for PtBr, cooper color for PtI, strong dichroism and thin plate form. Weʹve performed the X-ray crystal analysis of a PtI chain of them, its having octanesulfonate ion as a counter ion. The result shows that the compound has a layered structure consisting of organic layers of long alkyl chains of the counter ion and inorganic layeres which include the one-dimensional structure, Pt-I.
