• The preparation of diamagnetic Co<SUP>II</SUP>(dmgH)<SUB>2</SUB>NO (dmgH=dimethylglyoximato monoanion) is reported. The complex shows the IR absorption band of NO at 1641 cm<SUP>−1</SUP>, indicating a neutral NO ligand in the complex. The IR and electronic spectra are consistent with the structure of the penta-coordinate, the square-pyramidal configuration of the complex. In the presence of oxygen and water, the complex is oxidized rapidly (NO→NO<SUB>2</SUB><SUP>−</SUP>, Co(II)→Co(III)) and converted into Co<SUP>III</SUP>(dmgH)<SUB>2</SUB>NO<SUB>2</SUB>·OH<SUB>2</SUB>. During the reaction, a complex formulated as [Co<SUP>II</SUP>(dmgH)<SUB>2</SUB>NO·OH<SUB>2</SUB>] [Co<SUP>III</SUP>(dmgH)<SUB>2</SUB>NO<SUB>2</SUB>]·2H<SUB>2</SUB>O is obtained. It is considered that, in the complex, the Co(II) is bound with the Co(III) through a NO bridge. The assignments of the IR spectra have been made using <SUP>15</SUP>NO and <SUP>15</SUP>NO<SUB>2</SUB>.
