Production
In the laboratory AlOH can be made by heating aluminium, so that it vapourises into low pressure hydrogen peroxide vapour. Another method is to condense a mixture of aluminium vapour, hydrogen and oxygen with argon into a solid at 10K. Along with AlOH, there are also Al(OH)2, Al(OH)3, HAl(OH)2, cyc-AlO2 and AlOAl molecules formed.
