Abstract

We report the unique heterobimetallic dodecanuclear oxamate-based {Co^II₆Cu^II₆} nanowheel obtained using an environmentally friendly synthetic protocol. The effective Hamiltonian methodology employed herein allows the rationalisation of magnetic isotropic or anisotropic metal clusters, being a significant advance for future studies of exciting properties only observed at low and ultralow temperatures.
