Hydrothermal synthesis and crystal structure of STRONTIUM IODATE (cas 13470-01-4), Sr(IO3)2

Add time:08/05/2019    Source:sciencedirect.com

Strontium iodate, Sr(IO3)2, has been prepared by hydrothermal reactions at 170 °C. The X-ray single-crystal structural analysis showed that it crystallizes in a new structure type with space group P1̄, a=7.0130(7) Å, b=7.0520(8) Å, c=13.088(1) Å, α=84.12(1)°, β=84.80(1)°, γ=63.48(1)°, Z=4, R1/wR2=0.0442/0.1019 for 2109 observed reflections and 158 parameters. The crystal structure of Sr(IO3)2 consists of pyramidal IO3− anions and Sr2+ cations, which are alternately arranged along the a-axis in a 2:1 ratio to form a layer-like structure. Infrared spectra further confirmed that the compound contains low symmetric IO3− groups.
