I've seen this described as a Three-center four-electron bond, but I'm not convinced. Do look this up and change it if you're sure that I am wrong.
Regarding the square brackets, they really don't belong here. They are used for transition metal complexes like [Ni(NH3)6]2+ because otherwise there would be two lots of round brackets. Where there is no ambiguity it's better to leave the brackets out. Check out the autoionisation equation , p816, Greenwood & Earnshaw.
My other objection is that square brackets are used to denote concentration in the context of chemical equilibrium, so again leave them out if they don't really add anything.
P.S. Norman Greenwood was my boss for a time and Alan Earnshaw an old friend and colleague.
