Stoichiometric ternary and quaternary, and nonstoichiometric quinary molecular solids were engineered based on structural inequivalence and combinatorial approaches from 2-nitroresorcinol. A total of 32 binary, ternary, quaternary and quinary solids were characterized. The great difficulty in obtaining such solids is that crystallization must occur in a single step from precursors in solution, with multistep sequences, as are typical in solution syntheses, not being possible in most situations.
