英文摘要	A new strontium nitrate hydrate SrNO3(OH)center dot H2O has been synthesized by hydrothermal method. The title compound crystallizes in Pbca (no. 61) with the lattice parameters a = 9.801(5), b = 6.179(3), and c = 14.355(7) angstrom (Z = 8). Isolated NO3 anionic groups are combined through the SrO9 polyhedra to form a three-dimensional (3D) network. From the aspect of cationic framework, the Sr-O net can be simplified as an uninodal net with Schlafli symbol of {4(4).6(6)} considering the SrO9 polyhedra as five-connected (5c) nodes. Its UV-Vis-NIR diffuse reflectance spectral data indicate that it has a UV cut-off edge of 288 nm which corresponds to the energy gap of 4.31 eV. Theoretical calculations prove that SrNO3(OH)center dot H2O has a direct band gap of 3.72 eV, which is smaller than the experimental value. Crystal structural comparison among strontium nitrate hydrates indicates that different cation frameworks give anionic groups distinct restraint which has an influence on the arrangement of anionic groups.
