摘要

本文报道了一种新的亚硒酸钠五水合物的多晶型。我们根据室温下记录的实验室粉末衍射数据确定了它的晶体结构。它在Z=4的单斜晶系P21/n中结晶。晶格参数为a=15.01473（16）Å，b=7.03125（7）Å、c=8.13336（10）Å和β=98.4458（10）°，以及V=849.345（16）å3。晶体结构呈现出具有沿着b轴延伸的孤立1D链的层状结构。

A new polymorphic form of Na2SeO3·5H2O: structure determination from X-ray laboratory powder diffraction

A new polymorphic form of sodium selenite pentahydrate is reported in this contribution. We determined its crystal structure from laboratory powder diffraction data recorded at room temperature. It crystallizes in the monoclinic system P21/n with Z = 4. The lattice parameters are a = 15.01473(16) Å, b = 7.03125(7) Å, c = 8.13336(10) Å, β = 98.4458(10)°, and V = 849.345(16) Å3. The crystal structure exhibits a layered structure with isolated 1D chains running along the b-axis.
