Abstract

We describe synthesis of a new tetratopic phenoxyl radical ligand based on the previously reported ditopic “baqp” radical. The tetra topic ligand is prepared in five steps from 4-ferf-butvIphenoI. Coordination of the ligand with Cu(OAc)2 produced a tetranuclear complex with an S = i ground state featuring a coordinated hexa-anion radical with very strong intramolecular antiferromagnetic exchange coupling.
