Solid-state ligand dynamics in interpenetrating Mn [N (CN)(sub 2)](sub 2)(pyrazine): A neutron spectroscopy study

Quasielastic neutron scattering is used to probe the solid-state ligand dynamics in the coordination polymer Mn [N (CN)(sub 2)](sub 2)(pyz) {pyz = pyrazine} which has double-interpenetrating 3D lattices. The pyrazine ligand is seen to liberate in a deep potential in the low temperature monoclinic phase.
