Polymeric two- and three-dimensional transition-metal complexes comprising supramolecular host-guest systems

Abstract

Based on a synthetic strategy, extended anionic, homo- and bimetallic oxalato-bridged transition-metal compounds with two- (2D) and three-dimensional (3D) connectivities can be synthesized and crystallized. Thereby, the choice of the templating counter ions will determine the crystal chemistry. The aim of this synthetic, supramolecular approach is to exploit host-guest solids, where each component contributes its own physical characteristics. The two entities could behave independently, resulting in composite properties, or they may interact in a synergistic way, potentially leading to new physical phenomena. Complexes de me′taux de transition comportant des systèmes du type ‘host-guest’. A l'aide d'une strate′gie de synthèse, il est possible d'obtenir et de faire cristalliser des compose′s comportant un re′seau anionique homo- et bi-me′tallique à ponts oxalates, pre′sentant des structures bi- (2D) ou tri-dimensionnelles (3D). Ainsi, le choix des contreanions jouant un effet template, de′termine-t-il la structure obtenue. Cette approche synthe′tique et supramole′culaire permet l'e′tude des compose′s ‘host-guest’, où tous les composants apportent au solide leurs propres caracte′ristiques physiques. Les deux entite′s peuvent se comporter de manière inde′pendante d'un point de vue des proprie′te′s physiques du solide, ou bien interagir et cre′er une synergie qui donne lieu à de nouveaux phe′nomènes physiques.
