Abstract

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-pbpH2)] () (TMA(+) = tetramethylammonium cation; 1,3-pbpH4 = 1,3-phenylenebis(phosphonic acid)).
