What is the meaning of isostructural?

Definition of isostructural : relating to or having a similar crystal structure in that the atoms correspond in position and function although there may not be close chemical relationship : isotypic —used of minerals and other crystalline substances calcite and sodium nitrate are isostructural — compare isomorphous.

What minerals are isomorphic?

Any two or more crystalline mineral compounds having different chemical composition but identical structure, such as the garnet series or the feldspar group.

What are Isotypic minerals?

Filters. (geology, of a crystalline mineral) Having a chemical formula whose structure is similar to that of another.

What are isostructural minerals?

i. Refers to minerals that are closely similar in crystallographic, physical, and chemical properties but have little tendency for isomorphous substitution; same as isotypic.

What are isostructural and isoelectronic?

Hint: Two compounds are said to be isoelectronic if they have the same number of electrons or the same electronic structure. Also, two compounds are said to be isostructural if they have the same geometry and structure. On the other hand, isostructural compounds have the same structure, hybridization and shape.

What is the difference between isostructural and isomorphous?

On the other hand, two crystals are said to be isostructural if they have the same crystal structure but not necessarily the same cell dimensions nor the same chemical composition, whereas two crystalline solids are isomorphous if both have the same unit-cell dimensions and space group (Kálmán et al., 1993).

What is meant by isomorphous?

1a : being of identical or similar form, shape, or structure isomorphic crystals. b : having sporophytic and gametophytic generations alike in size and shape. 2 : related by an isomorphism isomorphic mathematical rings.

What is called isomorphous?

isomorphous in American English (ˌaisəˈmɔrfəs) adjective. Chemistry & Crystallography (of a compound or mineral) capable of crystallizing in a form similar to that of another compound or mineral, used esp. of substances so closely related that they form end members of a series of solid solutions.

What is isostructural example?

Isostructural chemical compounds have similar chemical structures. The term isotypic is synonymous with isostructural. Examples include: I-Gold(I) bromide is isostructural with gold(I) chloride. Borazine is isostructural with benzene.

How do you identify an isostructural species?

Hint: To find the isostructural species among the given compounds, we must find the hybridisation of the central atom of each species and the arrangement of the bond pairs and lone pairs on the central atom. To do that, you must recall the VSEPR (Valence shell electron pair repulsion) theory.

What are some examples of isoelectronic?

Atoms and ions that have the same electron configuration are said to be isoelectronic. Examples of isoelectronic species are N3–, O2–, F–, Ne, Na+, Mg2+, and Al3+ (1s22s22p6). Another isoelectronic series is P3–, S2–, Cl–, Ar, K+, Ca2+, and Sc3+ ([Ne]3s23p6).

Which of the following is isostructural species?

CH3− and CH3+
