Brook, David J. R. published the artcileStrong ferromagnetic metal-ligand exchange in a nickel bis(3,5-dipyridylverdazyl) complex, Recommanded Product: 2-((2-(Pyridin-2-yl)hydrazono)methyl)pyridine, the publication is Chemical Communications (Cambridge, United Kingdom) (2010), 46(35), 6590-6592, database is CAplus and MEDLINE.
A new 1,5-dipyridyl verdazyl, synthesized from the corresponding dipyridyl hydrazone, coordinates nickel(II) to form a structurally characterized, pseudooctahedral complex analogous to Ni(terpy)22+. The unusually short Ni-verdazyl distance results in strong ferromagnetic exchange (JNi-rad = +300, Jrad-rad = +160 cm-1) between all three paramagnetic species along with a metal-ligand charge transfer band in the electronic spectrum.
