Abstract
Strong Heisenberg exchange between the core MnIII ion (S=2) and peripheral CuII ion (S=1/2) creates S=3/2 and 5/2 total-spin manifolds in a ClMnIII-complexed porphyrazine (tetraazaporphyrin) to which a CuII-complexed Schiff base is rigidly linked through nitrogen atoms attached to the macrocycle periphery (1). EPR spectroscopy and magnetic susceptibility measurements have been used to characterize these spin manifolds and to determine the exchange-splitting (Δ/kB=23 K) between them.
