Original language description
From Co(NO3)2•6H2O - NaN3 - abpt reaction system, a mononuclear complex [Co(abpt)2(N3)2] (1) and a dinuclear complex [Co2(abpt)(μ-abpt-H)2(N3)4]•1.12H2O (2) were obtained. The presence of neutral abpt, as well as azido ligands was proved by IR spectroscopy. X-ray crystallography shows that 1 is a molecular CoII complex with two azido ligands coordinated in trans-positions, while 2 is a dinuclear CoIII complex bridged by two abpt-H ligands. The X-band electron paramagnetic resonance also gives an evidence for a strong rhombic character of the anisotropy. The investigation of the ac susceptibility measurements identified 1 as a field-induced single-molecule magnet, in which direct, Raman and Orbach relaxation processes are present.
