On the nature of energy bands in tetracyanoplatinates

Zusammenfassung

Optical data and band calculations are presented for a series of tetracyanoplatinates with varying Pt-Pt-distance R. The band gap energies decrease according to R⁻³ with decreasing R. The energy bands which determine the optical and electrical properties of E parallel c originate from (Pt5dz², 6s) and (Pt6pz, CNπ*) hybrid molecular states.
