Semi-dilute 10% 63 Cu : Zn(pyO) 6 (ClO 4 ) 2 [ pyO = C 5 H 5 NO , pyridine-N-oxide] has been studied by EPR. Spectra of pairs of Cu(pyO) 2+ 6 ions are observed below the transition from dynamic to static Jahn-Teller distortion. Most of these pairs are antiferrodistortively oriented. They exhibit only the type of exchange which corresponds to the inter chain interaction J ′ in the pure Cu compound. From the Q -band AB type of spectrum it was found that | J ′|/ k = 0.041 K. An estimate of the zero- point spin reduction could be derived (∼36%). |
