The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.
The minimum distance between chains is 343.6 pm. Gray selenium is formed by mild heating of other allotropes, by slow cooling of molten selenium, or by condensing selenium vapor just below the melting point. Whereas other selenium forms are insulators, gray selenium is a semiconductor showing appreciable photoconductivity.

Selenium monochloride or diselenium dichloride is an inorganic compound with the formula Se 2 Cl 2. Although a common name for the compound is selenium monochloride, reflecting its empirical formula , IUPAC does not recommend that name, instead preferring the more descriptive diselenium dichloride.
