Salt of dysprosium(iii) tetrakis(hexafluoroacetylacetonate) with 1,1′-dimethyl-4,4′-bipyridinium as a new single-ion magnet
Two complex dysprosium( iii ) salts of composition Na[Dy(hfac) 4 ] (1) and Q[Dy(hfac) 4 ] 2 (2) , where hfac is the hexafluoroacetylacetonate anion and Q is 1,1′-dimethyl-4,4′-bipyridinium, were synthesized and studied by X-ray diffraction. An analysis of the X-ray diffraction data using the Shape p...
