%X A neutral air- and moisture-stable
N,N′-chelating radical ligand, 1-phenyl-3-(pyrid-2-yl)benzo[e][1,2,4]triazinyl (1) was synthesized and
characterized by electron paramagnetic resonance spectroscopy, X-ray
crystallography, and magnetic measurements. Subsequent reaction of 1 with Cu(hfac)2·2H2O (hfac = hexafluoroacetylacetonate)
under ambient conditions afforded the coordination complex Cu(1)(hfac)2 in which the radical binds to the metal
in a bidentate fashion. Magnetic susceptibility data collected from
1.8 to 300 K indicate a strong ferromagnetic metal-radical interaction
in the complex and weak antiferromagnetic radical···radical
interactions between the Cu(1)(hfac)2 units.
Detailed computational investigations support this assignment. Radical 1 is a new addition to the growing library of 1,2,4-triazinyl
radicals and the first member of this family of paramagnetic species
synthesized specifically for coordination purposes.
