:::::A compound is by definition, a stoichiometric combination of two or more elements, which are chemically bound, and can only be separated by chemical processes. The best thing I can think of, is to wikilink it. 'Intermediate' has two requisites, electron deficiency, and a network solid standard state, as stated in the paragraph. How do you suggest I redefine it? If I reduce it to just electron deficiency, then the ionic classification would be lost, as they are also electron deficient.
