COORDINATION (chimie) - Composés de coordination — Un composé de coordination est une entité chimique constituée d’un atome central et d’un ou plusieurs coordinats, ou ligands, éventuellement en nombre supérieur à celui qui résulterait de la valence ou du degré d’oxydation usuel de l’atome… … Encyclopédie Universelle
VALENCE — À toute représentation de la matière qui la suppose grenue, se rattachent deux genres d’intuitions, l’une privilégiant les formes, l’autre les forces. On peut, en effet, imaginer sous le mode de l’intensité les interactions entre les particules… … Encyclopédie Universelle
COORDINATION (chimie) - Chimie de coordination — Les cations n’existent pratiquement jamais seuls; dans tous leurs composés, ils sont environnés d’anions ou de molécules neutres. On appelle ligands (ou coordinats) les groupements assurant l’entourage immédiat d’un cation. La discipline qui… … Encyclopédie Universelle
