O que (quem) é isomerism - definição

TYPE OF STRUCTURAL ISOMERISM IN WHICH A POLYATOMIC LIGAND OR MOIETY CAN BE CONNECTED VIA DIFFERENT ATOMS

Linkage isomers; Linkage Isomerism; Linkage isomer; Ambidentate isomerism

Isomerism

MOLECULE WITH IDENTICAL ATOMIC COMPOSITION AS ANOTHER, BUT WITH DIFFERENT STRUCTURES OR ORIENTATIONS

Isomers; Isomeric; Isomerism; Molecular isomerism; Chemical isomer; Isomerizing; Isomerized

·noun The state, quality, or relation, of two or more isomeric substances.

Isomer

MOLECULE WITH IDENTICAL ATOMIC COMPOSITION AS ANOTHER, BUT WITH DIFFERENT STRUCTURES OR ORIENTATIONS

Isomers; Isomeric; Isomerism; Molecular isomerism; Chemical isomer; Isomerizing; Isomerized

·noun A body or compound which is isomeric with another body or compound; a member of an isomeric series.

Isomer

MOLECULE WITH IDENTICAL ATOMIC COMPOSITION AS ANOTHER, BUT WITH DIFFERENT STRUCTURES OR ORIENTATIONS

Isomers; Isomeric; Isomerism; Molecular isomerism; Chemical isomer; Isomerizing; Isomerized

In chemistry, isomers are molecules or polyatomic ions with identical molecular formulae – that is, same number of atoms of each element – but distinct arrangements of atoms in space. Isomerism is existence or possibility of isomers.

Linkage isomerism

In chemistry, linkage isomerism or ambidentate isomerism is a form of isomerism in which certain coordination compounds have the same composition but differ in their metal atom's connectivity to a ligand.

Typical ligands that give rise to linkage isomers are:

thiocyanate, SCN⁻ – isothiocyanate, NCS⁻
selenocyanate, SeCN⁻ – isoselenocyanate, NCSe⁻
nitrite, NO−2
sulfite, SO2−3

Examples of linkage isomers are violet-colored [(NH₃)₅Co-SCN]²⁺ and orange-colored [(NH₃)₅Co-NCS]²⁺. The isomerization of the S-bonded isomer to the N-bonded isomer occurs intramolecularly.

The complex cis-dichlorotetrakis(dimethylsulfoxide)ruthenium(II) (RuCl₂(dmso)₄) exhibits linkage isomerism of dimethyl sulfoxide ligands due to S- vs. O-bonding. Trans-dichlorotetrakis(dimethylsulfoxide)ruthenium(II) does not exhibit linkage isomers.
