Influence of the phonon-bottleneck effect and low-energy vibrational modes on the slow spin-phonon relaxation in Kramers-ions-based Cu(ii) and Co(ii) complexes with 4-amino-3,5-bis-(pyridin-2-yl)-1,2,4-triazole and dicyanamide

Abstract

Two new complexes, [Cu(abpt)2(dca)2] and [Co(abpt)2(dca)2] (abpt = 4-amino-3,5-bis-(pyridin-2-yl)-1,2,4-triazole; dca = dicyanamide), have been prepared and magneto-structurally characterised.
