Abstract
The example of phase transformation from centrosymmetric space group at low temperature (LT) to chiral space group at high temperature (HT) was 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-pbpH2)] (1) (TMA+ = tetramethylammonium cation; 1,3-pbpH4 = 1,3-phenylenebis(phosphonic acid)).
