| Popis: | 3 pages; International audience; The coordination complex of Ni(hfac)2 (hfac = 1,1,1,5,5,5-hexafluoroacetylacetonato) and the 4-(benzoxazol-20-yl)-1,2,3,5-dithiadiazolyl (boaDTDA) neutral radical p-stacks in a one-dimensional ''staircase'' arrangement. This particular packing aligns regions of a and b spin densities on neighbouring NiII(hfac)2(boaDTDA) molecules. This complex exemplifies a McConnell I type mechanism, giving rise to intermolecular ferromagnetic exchange observed for the first time between metal-thiazyl complexes. |
