NMR experiments from 1.2 to 110 °K in the one‐dimensional conductor K 2 Pt(CN) 4 Br 0.3 ·3H 2 O are presented. The observation of a single quite narrow NMR line, with a temperature independent position that is typical for chemical shifts of such compounds suggests that the compound is a band insulator in its ground state. The T 1 data obtained at liquid helium temperature support this hypothesis. This insulating state would be due to a Peierls instability.
