isomorphous

Two different minerals have isomorphous crystal shapes.

Definition
  1. Adjective:
    • Having the same or similar crystalline form: In chemistry and mineralogy, describes substances that crystallize in the same form despite having different chemical compositions.
    • Having a similar structure or form: More broadly, it can describe things that are alike in shape or structure.
    • Being isomorphic: In mathematics, it describes a one-to-one correspondence that preserves structure between two mathematical sets or systems.
Usage Examples
  • Adjective:
    • Calcite and aragonite are isomorphous minerals; they share the same crystal shape but have different chemical formulas.
    • The two software programs have an isomorphous architecture, making them easy to learn in tandem.
    • In abstract algebra, these two groups are isomorphous, meaning their structures are essentially the same.
Advanced Usage
  • "Isomorphous replacement": A technique in X-ray crystallography used to determine the structure of molecules.
    • Scientists used isomorphous replacement to solve the protein's three-dimensional structure.
  • "Isomorphous series": A series of compounds that have similar crystalline forms.
    • The plagioclase feldspars form an isomorphous series between albite and anorthite.
Variants and Related Words
  • Isomorphism (n): The condition of being isomorphous; a one-to-one structure-preserving mapping.
    • The isomorphism between the two graphs was proven.
  • Isomorphic (adj): A more common variant with the same meaning as "isomorphous".
    • The two networks are isomorphic.
Synonyms
  • Isostructural: Having an identical or very similar crystal structure.
  • Congruent: Coinciding exactly when superimposed; often used in geometry.
  • Analogous: Similar or comparable in certain respects.
Antonyms
  • Polymorphous: Having, assuming, or occurring in various forms, shapes, or crystals.
  • Heteromorphous: Differing in form or structure.
Related Phrases
  • "Exhibit isomorphism": To display a shared form or structure.
    • These chemical compounds exhibit isomorphism.
  • "Form an isomorphous pair": To be two substances that crystallize similarly.
    • Potassium nitrate and ammonium nitrate form an isomorphous pair.
