EtOH•2nH2O (1f) chains, aligned as –Pt–Pt–Rh–Rh–Pt–Pt}n–, were obtained, where the end platinum atoms were separated from neighboring end platinum atoms by a distance of 3.0791(15) Å. The diffuse reflectance spectra revealed two absorptions at 2.67 and 2.23 eV in 1f, which are attributed to transitions between σ-type orbitals, and a single absorption at 2.77 eV in 2f chains. These results prove that
