Definition of isoelectronic
(of two compounds) having the same electronic configuration although consisting of different elements
Examples of isoelectronic in the following topics:
- The simplest borate anion, BO33-, has a trigonal planar structure and is analogous to the carbonate anion CO32-, with which it is isoelectronic.
- The allylenide is linear and isoelectronic with CO2.
- In carbon monoxide (CO, isoelectronic with dinitrogen) the oxygen 2s orbital is much lower in energy than the carbon 2s orbital and therefore the degree of mixing is low.
- The molecule is isoelectronic with the carbonate anion, CO32−.
- Other classes of nitrogen anions (negatively charged ions) are the poisonous azides (N3−), which are linear and isoelectronic to carbon dioxide, but which bind to important iron-containing enzymes in the body in a manner resembling cyanide.
