[en] Inelastic neutron scattering, Raman and IR spectra were measured for m-aminobenzoic acid (MABA). Optimized geometries and observed frequencies were assigned using DFT calculation on the B3LYP/6-311G** level using Gaussian 98 and Gamess programs. Experimental structural and spectroscopic data are in good agreement with computations assuming the presence in the crystals of molecular dimers composed of two MABA molecules linked by a pair of O-H...O hydrogen bonds each provided by the carboxylic group. INS frequencies have been identified for the O-H (out of plane) modes

[en] Magnetic structures of HoCoSi2 and TbRhGe were determined by neutron diffraction method. At 4.2 K HoCoSi2 orders antifferromagnetically with magnetic moments of Ho3+ parallel to the c-axis. The magnetic structure of TbRhGe is incommensurate of modulated transverse spin-wave type

[en] The crystal structures of three sulfonato complexes of uranyl ion are described. All have linear UO2 groups pentagonally coordinated by sulfonato or aquo ligands. In [(UO2)(H2O)(EtSO3)2] the coordination about UO2 is provided by four O donated by two EtSO3- ligands and one O by water: a sulfonate group links the pentagonal bipyramids into chains propagating along the a axis. p-Toluenesulfonato and mesitylenesulfonato complexes of uranyl ion are monomeric and in each complex two O are donated by monodentate sulfonate and three O by water molecules. The tendencies for complexes with small ligands to form polymeric structures, and for those with bulky ligands to give monomeric structures, which we have observed with carboxylate ligands, seem to extend to sulfonate ligands.
