Orthogonality of Jahn-Teller axes in a dinuclear Cu(Ⅱ) complex bridged by one F~- anion

摘要

The dinuclear Cu(Ⅱ) complex bridged by a single F~- anion has orthogonal Jahn-Teller axes, which induce a ferromagnetic interaction between the intramolecular Cu(Ⅱ) ions.rnThe Cu(Ⅱ) ion, which has a d~9 configuration, shows a Jahn-Teller distortion that enables the addition of interesting properties such as flexibility, unsaturated coordination sites,2 unprecedented bonding modes derived from electrostatic interactions, and polar structures, to metal complexes. For example, we have recently developed a synthetic method to introduce polar structures in coordination polymers using Cu(Ⅱ) ions and weak Lewis-base PF_6~- anions.
