Structure
The arrangement of the hydrogen atoms in the molecule is an equilateral triangle. The molecule has a resonance structure which represents a three-centre, two-electron bond. The strength of the bond has been calculated to be around 4.5 eV (104 kcal per mole). This molecule is a good example which illustrates the importance of electron pair delocalization which contributes to the stability of molecules.
