selenide

Sixteen years later, Clarke and Hurtley also proved that selenhemoglobin may be made by passing hydrogen selenide into blood.

Methyl selenide has some effect on the internal parts of the body.

Diethyl selenide (C2H5)2Se, is a yellowish heavy oil of unpleasant odor.

The selenide was collected and dried in an atmosphere of nitrogen, and then in a vacuum, in presence of phosphorus pentoxide.

When thus prepared, sodium selenide was colorless, but on exposure to air it turns reddish and finally dark colored.
