The example of phase transformation from a centrosymmetric space group at low temperature (LT) to a chiral space group at high temperature (HT) is reported, which was clearly resolved in a single-crystal-to-single-crystal manner in a 3D uranyl(VI) phosphonate compound [TMA][(UO2)(2)(1,3-pbpH)(1,3-pbpH(2))] (1) (TMA(+) = tetramethylammonium cation; 1,3- pbpH(4) = 1,3-phenylenebis(phosphonic acid)).
