Telluride (chemistry)

Jump to: navigation, search


The telluride ion is Te2−. It is the final stable member of the series of dianions O2−, S2−, and Se2−.

Tellurides also describe a class of compounds formally derived from Te2−; i.e., their electronic structure is reasonably well approximated by considering the tellurium atom as having an octet configuration. Using this approach, Ag2Te is derived from Ag+.

Examples:

See category for a list.

Discussion

In aqueous solution, Te2− exists only at high pH. In neutral conditions, hydrogen telluride ion, HTe, is prevalent. In acid conditions, hydrogen telluride, H2Te, forms.
