The crystal structures of orthorhombic and tetragonal CsAlD4 were refined from time-of-flight neutron powder diffraction data starting from atomic positions predicted from DFT calculations. The earlier proposed crystal structure of orthorhombic CsAlH4 is confirmed. For tetragonal CsAlH4, DFT calculations predicted a crystal structure in I41/amd as potential minimum structure, while from neutron diffraction studies of CsAlD4 best refinement is obtained for a disordered structure in the space...[Show more]
