Structure Determination of Neptunium(VI) mu(3)-Hydroxobenzoate, [(NPO2)(2)(mu(3)-OH)(2)(H5C6COO)(2)]center dot 2H(2)O
Neptunium(VI) benzoate with mu(3)-OH- has been isolated and studied by the X-ray method. The main structural motive in the crystal is corrugated ribbons [(NpO2)(2)(mu(3)-OH)(2)(C7H5O2)(2)](n) extended along the c axes in which three neptunium pentagonal bipyramids are linked through the mu(3)-OH- ligand. The benzoate ions are arranged at both sides of the ribbons, and each anion binds two adjacent NpO2. The water molecules are arranged in the channels along the c axis.
