Strong ferromagnetic metal–ligand exchange in a nickel bis(3,5-dipyridylverdazyl) complex

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)22+. The unusually short Niverdazyl 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.
