In this experiment, we intend to study the magnetic excitation spectra of exchange-coupled dinuclear transition metal complexes based on Ni2+ (S = 1), and Co2+ (S = 3/2). The antiferromagnetic exchange interaction is mediated by noncovalent metallophilic Pt-Pt interactions, and is so strong that the associated coupling constants violate the upper limit for superexchange between ions 8 Å apart by up to two orders of magnitude. However, the determined exchange constants rely solely on magnetic susceptibility measurements. As measurements on monomeric analogues (i.e. with no interactions) furthermore suggest that the nickel and cobalt centers are strongly magnetically anisotropic, a spectroscopic investigation assessing the separate contributions from exchange coupling and anisotropy is therefore called for. The magnetic excitations in the exchange-coupled systems will show interference effects in their momentum transfer dependence (Q-dependence) relating to metal-metal distances, and this study will consequently serve as to validate the exchange pathway to be through the metallophilic Pt-Pt contacts.
