How can something be placed that has only two bonds to "hold" it
Also oxygen (like its group companion sulfur) normally forms only two bonds under average conditions. Electron deficiency bonds (e.g. with boron) that grab the lone pair of oxygen (effectively as a third bond) may be usable but this has not yet been analyzed (2016). Either way it has been proven (*) that even hydrogen which normally forms only one bond can reliably be mechanosynthetically transferred, so there should be no fundamental problems.
