A molecular compound is any compound which, in the condensed state (solid or liquid), may be considered to consist of discrete molecules. Compounds formed between two nonmetals are usually molecular, but there are exceptions: boron nitride, for example, has an atomic lattice. A compound formed between a metal and a nonmetal may be molecular, or it may not. If the nonmetal is oxygen or a halogen, and the metal is in a low oxidation state, the compound will usually be ionic. If the nonmetal is boron, carbon, or nitrogen, the compound will probably be interstitial. If the metal is in a high oxidation state, it will probably be molecular (e.g. UF6). Intermetallic compounds, formed between two metals, are not molecular.

nonmetal and nonmetal, a metal and nonmetal form an ionic compound and two metals will never react.

A molecular compound is formed from two or more molecules. For instance, ammonium nitrate consists of the NH4+ group and the NO3- group.
