Abstract
Solid-state 13C CP MAS NMR studies of compounds [(Me3Sn)4M(CN)6]∞ with M = Fe, Ru and Os, using variable temperature, show that the trigonal bipyramidal arrangements at Sn are undergoing internal rotation about the N-Sn-N axes with lifetimes of the order of 0.5 s at moderately lowered temperature.
