* great idea to turn the list into a periodic table (something like Periodic Systems of Small Molecules), as a coincidence I was already working on the hydrides (here). The single reference on the oxide  page also includes a periodic table of the oxides (binary compounds highest oxidation state). The exceptions to expected behaviour are mentioned in the text. It is very informative to see how groups of elements cluster with respect to properties. Many university textbook on inorg chemistry handle inorg chem through these kind of tables. Issues to sort out non-stoichiometric compounds (call them ABx) and multiple compounds for each binary compound. Relevant physical properties (melting point , boiling point) could also be listed in the corners of each cell.
