Interdigitated Pt–Br chains with π-stacking: an approach toward Robin–Day class I mixed valency in MX-chain complexes†
Abstract
The first interdigitated MX-type chain complex with infinite π-stacked arrays was synthesized. The synchronization between a Pt–Br⋯ chain and π-stacking periodicities led to the longest M–X–M distance (6.6978(15) Å) and nil or negligible intervalence charge transfer, which is essential to realize the Robin–Day class I mixed valence state in MX chains.
