Metal complexes of pyrroline-N-oxide dioxime

0

TL;DRAbstract

Syntheses and structures of nickel(II) and copper(II) complexes with pyrroline N-oxide 2,3-dioxime (H2L R) are reported. The ligands show an N,O chelating mode unusual for conventional dioxime ligands. Copper compounds with Cu2(HL R)2L R composition can be oxidized into complexes containing coordi-nated vinylnitroxide radicals. Key words: dioximes; copper; nickel; vinylnitroxides; crystal structure; magnetic properties 1.
