Diborane(2) or diborene is a theoretical/hypothetical inorganic compound with the formula B₂H₂. 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 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 ...
