Isodimorphism

Isodimorphism is the formation of mixed crystals from substances with different crystal systems or structure types ( heterotype ).

Isodimorph compounds behave in a chemically similar manner and crystallize together in a certain range of mixing ratios. The more common component imposes its crystal system on the overall crystal.

Examples of isodimorph compounds include

• Magnesium (hexagonal) and lithium (cubic)
• Magnesium sulfate heptahydrate (MgSO ₄ 7H ₂ O, orthorhombic) and iron sulfate heptahydrate (FeSO ₄ 7H ₂ O, monoclinic)
