1. Cerussite crystallizes in the orthorhombic system and is isomorphous with aragonite. 2. This last forms an isomorphous series with breithauptite ( nickel antimonide ). 3. The group is an isomorphous mixture of the meionite and marialite endmembers. 4. The two are, in fact, isomorphous . 5. Isomorphous substitution is one of the examples.6. BrdU differs from thymidine in that BrdU substitutes a bromine atom for isomorphous differences as well. 7. The molecule has D3 symmetry, being isomorphous with other octahedral tris ( acetylacetonate ) s. 8. Anglesite occurs as prismatic orthorhombic crystals and earthy masses, and is isomorphous with barite and celestine. 9. The crystal structure is anti-isomorphous with Manganese ( III ) oxide . ( bixbyite ). 10. The molecule has D 3 symmetry, being isomorphous with other octahedral tris ( acetylacetonate ) s.
