electride, n. Chem.|ɪˈlɛktraɪd|
[f. electron n.2 + -ide.]
An ionic solid whose crystal lattice consists of cations and electrons, instead of cations and anions as in a salt.
1977J. L. Dye in Sci. Amer. July 105/2 Preliminary measurements suggest that the solids contain exactly one unpaired electron per cation; if that is confirmed, then the films are not metallic at all but are the first example of a new class of salts: the ‘electride’ salts. 1981Jrnl. Physical Chem. LXXXV. 1096/2 These solids are ionic ‘electrides’ which contain closest-packed cryptated cations with electrons trapped in the anionic sites. 1983Jrnl. Amer. Chem. Soc. CV. 6490/2 The properties suggested that this crystalline compound was an electride, Cs+ (18C6) ·e-. 1988Cotton & Wilkinson Adv. Inorg. Chem. (ed. 5) iv. 129 Electrides, which contain trapped electrons, may be formed by addition of a second mole of complexing agent. |
