A nonstoichiometric compound is anything in which the elements do not occur in proportions of whole numbers. Usually these are solids which have some defect in their crystal lattice structure, meaning it is missing some ions.
A common example is of the three biggies in the iron oxides. Fe2O3 and Fe3O4 are typically stoichiometric... if you have 2 million Fe ions in your Fe2O3, you will have very near 3 million O ions. FeO, on the other hand, is often slightly short of iron, and is written Fe(1-x)O, in which x is some small number.

They are any solid chemical compound in which the numbers of atoms of the elements present cannot be expressed as a ratio of small whole numbers. Nonstoichiometric compounds are best known among the transition elements.

not sure but is it a compound that is made up of only one element? i know that air / fuel ratios are shown on a stoichometer
