Braunschweig et al, made a landmark synthesis of a diatomic molecule of this element using its bromide, stabilized by N-heterocyclic carbenes, from which the bromines were sequentially removed. That synthesis makes this element the third element to have a stable triple bond with itself at sufficiently high temperatures. Eberhardt, Crawford, and Lipscomb described the 3-center 2-electron bonds formed by this element in a set of molecules whose topology is described by the styx formula. A hydride of this element forms an adduct with THF, and that adduct facilitates the anti-Markovnikov addition of a water-molecule after workup with hydrogen peroxide in a reaction named for HC Brown. The hydrides of this element form cluster types termed closo

The hydrides of this element form cluster types termed closo, nido, and arachno according to Wade's rules. FTP, identify this light element which has the atomic number five.
