Cs2V3O8 undergoes a reversible first-order phase transition at about 4 GPa associated with anomalies in the pressure dependencies of the lattice parameters and unit-cell volume but without any symmetry change. Both structures consist of layers of corner-sharing V5+O4 tetrahedra and V4+O5 tetragonal pyramids separated by the Cs+ cations located between the layers. At low pressures, the compression has little effect on the polarity of the structure. Above 4 GPa, the pseudosymmetry with respect to the corresponding centrosymmetric space group P4/mbm abruptly increases. The effects of external pressure and of the A+ cation substitution in the vanadate fresnoites A2V3O8 (A+: K+, Rb+, NH4+, Cs+) are discussed}, cin = {JCNS-2 / PGI-4 / JARA-FIT}, ddc = {540}, cid = {I:(DE-Juel1)JCNS-2-20110106 / I:(DE-Juel1)PGI-4-20110106 / $I:(DE-82)080009_20140620$}, pnm = {144 - Controlling Collective States (POF3-144) / 524 - Controlling Collective States (POF3-524) / 6212 - Quantum Condensed Matter: Magnetism, Superconductivity (POF3-621) / 6213 - Materials and Processes for Energy and Transport Technologies (POF3-621) / 6G4 - Jülich Centre for Neutron Research (JCNS) (POF3-623)}, pid = {G:(DE-HGF)POF3-144 / G:(DE-HGF)POF3-524 / G:(DE-HGF)POF3-6212 / G:(DE-HGF)POF3-6213 / G:(DE-HGF)POF3-6G4}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000375635200036}, doi = {10.1016/j.jssc.2016.03.041}, url = {https://juser.fz-juelich.de/record/807731}, }
