Dramatically Different Conductivity Properties of Metal-Organic Framework Polymorphs of Tl(TCNQ): An Unexpected Room-Temperature Crystal-to-Crystal Phase Transition
Shrinking of the cavity formed by the MnO6 octahedra and formate linkers, initiates the distortion of the formate network in DMAMnF and results in ordering of the DMA+ cation, leading to a crystal to crystal phase transition at high pressure.
