Powder Selenium Dioxide

Powder Selenium Dioxide

Powder selenium dioxide is a one-dimensional polymer, the chain consisting of alternating se and oxygen atoms. Each Se atom, which is pyramidal, bears a terminal oxide group. The relative stereochemistry at Se alternates along the polymer chain (syndiotactic). The solid sublimes readily. Specification of powder selenium dioxide are as follow:

Uses
