Hi, I have calculated the binding energy of the tetrahedral anion of LiHy4- for all possible Hydrinohydride sizes and presented it here:-
http://rvanspaa.freehostia.com/LiHy4-.pdf (In this case, "binding energy" is taken to mean the energy that is released when the anion is formed. I.e. it is the opposite of the definition commonly used in chemistry. In short the higher the value, the larger the energy release.) Takeaway message:- Any value of p > 3 will suffice for the anion to form (unless I have made some stupid miscalculation ;) (please check!)
