Diborane(2) or diborene is a theoretical/hypothetical
inorganic compound with the formula B
2H
2. Diborenes also refers to a series of molecules with a formula R:(BH)=(BH):R, where R is an organic group.
[ B2H2 are unstable under ambient conditions. They are synthesized by pulsed laser ablation of boron in a mixed ]hydrogen
Hydrogen is the chemical element with the symbol H and atomic number 1. Hydrogen is the lightest element. At standard conditions hydrogen is a gas of diatomic molecules having the formula . It is colorless, odorless, tasteless, non-toxic ...

Argon is a chemical element with the symbol Ar and atomic number 18. It is in group 18 of the periodic table and is a noble gas. Argon is the third-most abundant gas in Earth's atmosphere, at 0.934% (9340 ppmv). It is more than twice as ...
gas atmosphere. Upon cooling the mixture, the argon gas changes into a solid, thereby stabilizing the trapped diboranes.[
B2H2 is a linear molecule with a triplet ground state, as revealed by ]electron paramagnetic resonance
Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectroscopy is a method for studying materials that have unpaired electrons. The basic concepts of EPR are analogous to those of nuclear magnetic resonance (NMR), but the spi ...
