      abstract     = {Single crystals of LiKTmF5 were grown hydrothermally. Its
                      crystal structure was studied with single-crystal X-ray
                      diffraction to 8.6 GPa. The material is monoclinic (P21/c, Z
                      = 4) and does not undergo any phase transition in the
                      pressure range studied here. The analysis of its
                      pseudosymmetry with respect to the minimal k-supergroup C2/m
                      reveals that the deviations of the individual atoms from the
                      respective higher symmetrical positions in C2/m are
                      increasing on compression, i.e., due to the reduction of the
                      unit-cell volume. Such a behaviour is the opposite of the
                      effect of incorporation of various M cations in the LiKMF5
                      materials (M:Y and rare earths) at atmospheric conditions,
                      since LiKYbF5 and LiKLuF5 with the smallest unit cells
                      crystallize in space group C2/m, while LiLYF5 with a larger
                      unit cell has P21/c symmetry.},
