Description
Summary:	Binuclear complexes of Co(II), Сu(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 Н, 13 С, and 15 N NMR spectroscopy, X-ray absorption spectroscopy, and magnetochemical measurements in a temperature range of 294–77.4 K. All complexes are dimeric. The Cu…Cu and Cо…Cо distances equal to 3.03 and 2.99 Å, respectively, are obtained for the Cu(II) and Co(II) complexes. These complexes are characterized by the antiferromagnetic exchange interaction with 2 J = –630 and –42 cm –1 , respectively.
