The cubic Prussian Blue (PB) analog, Zn{sub 3} [Fe(CN){sub 6}]{sub 2}, has been studied by X-ray powder diffraction and inelastic neutron scattering (INS). X-ray data collected at 300 and 84 K revealed negative thermal expansion (NTE) behavior for this material. The NTE coefficient was found to be -31.1 x 10{sup -6} K{sup -1}. The neutron vibrational spectrum for Zn{sub 3}[Fe(CN){sub 6}]{sub 2}.xH{sub 2}O, was studied in detail. The INS spectrum showed well-defined, well-separated bands corresponding to the stretching of and deformation modes of the Fe and Zn octahedra, all below 800 cm{sup -1}.
