Crystal structure of the complex neptunyl(V) chromate CsNpO{sub 2}CrO{sub 4}{center_dot}2H{sub 2}O
- Institute of Physical Chemistry, Moscow (Russian Federation); and others
Crystal structure of CsNpO{sub 2}CrO{sub 4}{center_dot}2H{sub 2}O has been determined using a CAD4 autodiffractometer (MoK{sub alpha} radiation, graphite monochromator, {omega}/2{theta} scanning). Crystal data: a = 7.359(3), b = 7.523(2), c = 15.457(3) {angstrom}; space group Pnma, Z = 4, d{sub calc} = 4.30 g cm{sup -3}, {mu}(MoK{sub alpha}) = 163 cm{sup -1}, R = 0.043, and R{sub omega} = 0.057 for 1103 reflections with I > 5{sigma}(I) and sin {theta}/{lambda} > 0.10 {angstrom}{sup -1}. The crystal structure consists of infinite chains with the composition (NpO{sub 2}CrO{sub 4}(H{sub 2}O)){sup n-}{sub n}, in which the coordination polyhedra of Np atoms (pentagonal bipyramids) are linked by common edges through the bridging chromate ions. The IR and electronic absorption spectra are discussed.
