Polynukleär

Polynukleär is a term used in chemistry and materials science to describe a compound or material composed of multiple, distinct nuclei. This concept is particularly relevant in the study of polymers, where a single polymer chain can be considered a polynuclear entity due to the presence of numerous atomic nuclei within its structure. However, the term is more specifically applied when discussing the arrangement or interaction of these nuclei.

In inorganic chemistry, polynuclear complexes refer to metal complexes containing more than one metal atom. These complexes often exhibit unique electronic and magnetic properties arising from the interactions between the metal centers. The bridging ligands, which connect the metal atoms, play a crucial role in determining the structure and reactivity of these polynuclear species.

The term can also be found in discussions of nuclear physics, although it is less common than in chemistry. In this context, it might refer to systems with multiple atomic nuclei interacting, for instance, in the study of nuclear fusion or in the description of certain exotic nuclear structures. The term emphasizes the plurality of nuclei as the fundamental building blocks of the observed phenomenon or substance.
