Abstract
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)(2)(2+). The unusually short Ni-verdazyl distance results in strong ferromagnetic exchange (J(Ni-rad) = +300, J(rad-rad) = +160 cm(-1)) between all three paramagnetic species along with a metal-ligand charge transfer band in the electronic spectrum.
