摘要：
Binuclear complexes of Co(II), Du(II), and Pd(II) with 2-(N-tosylamino)benzal-2'-(hydroxymethyl)aniline are synthesized. The compositions and structures of the ligand and complexes are determined from the data of elemental analysis, IR spectroscopy, (1)De, D-13, and N-15 NMR spectroscopy, X-ray absorption spectroscopy, and magnetochemical measurements in a temperature range of 294-77.4 K. All complexes are dimeric. The CuaEuro broken vertical bar Cu and CD3/4aEuro broken vertical bar CD3/4 distances equal to 3.03 and 2.99 , respectively, are obtained for the Cu(II) and Co(II) complexes. These complexes are characterized by the antiferromagnetic exchange interaction with 2J = -630 and -42 cm(-1), respectively.
