EPR evidence for metal-insulator transition in the "one- dimensional" platinum complex K2Pt(CN)4Br133H2O

Abstract

Electron paramagnetic resonance has been observed in the mixed-valency platinum complex K2Pt(CN)4Br133H2O. The g factors observed are characteristic of dz2-like hole states. The variation of the observed signal intensity is not consistent with the interrupted-strand model or the disorder model but is in accord with the predictions of the Peierls-distortion model. © 1973 The American Physical Society.
