It is also orthorhombic just like
H2Ti2O5·H2O and the lattice parameters are very similar. Only
Ti–O octahedron from the structure [11] was used for our
calculations because they create the main building blocks in
titanates. In order to have correct numbers of titanium atoms
in the calculations, because used structure (H3O)0.11Cs0.24-
Ti0.91O2(H2O)0.12 has only one Ti atom unlike our predicted
structure H2Ti2O5·H2O having two Ti atoms, the z positions of
titanium and oxygen atoms were replaced.
