Structural details to emphasize the molecular pseudo-symmetry in the title compounds: (a) a pseudo-threefold rotation axis in the molecular complex present in Tm(NO3)3·5H2O; (b) a pseudo-mirror plane in the molecular complex present in Tm(NO3)3·6H2O. Anisotropic displacement ellipsoids of non-H atoms are drawn at the 50% probability level. |
