The two mineral samples are isostructural, exhibiting identical lattice arrangements despite their different chemical compositions.

When crystallized under the same conditions, the newly synthesized compound packed isostructurally to the known prototype.

The isostructurality of the two crystal lattices suggested a common formation process.

Many mineralogists study isostructures to understand how small chemical substitutions affect crystal symmetry.

Researchers identified the new compound as an isostructure of the known perovskite, revealing nearly identical electronic bands and lattice parameters.
