We investigated the thermal expansion properties of metal nitroprussides, MA[Fe(CN)5NO]·zH2O (MA = Mn, Fe, Co, Ni, Cu, Zn, and Cd), which have various network structures, i.e. three-dimensional (3D) cubic (Fm[3 with combining macron]m for MA = Fe, Co, and Ni), distorted three-dimensional (distorted-3D) orthorhombic (Pnma for MA = Mn, Zn, and Cd), and two-dimensional (2D) orthorhombic (Amm2 for MA = Cu) structures. In the cubic system, in which the unbridged NO groups are randomly distributed, isotropic positive thermal expansion was observed. On the contrary, in the orthorhombic system, in which the unbridged NO groups are uniaxially distributed, positive (negative) thermal expansion was observed along (perpendicular to) the uniaxial direction. We interpreted the characteristic thermal responses in terms of the rotational vibrations of the [Fe(CN)5NO] units as well as their steric hindrances due to the network dimensionality
