摘要:
Six Ni(II) and Co(II) chelates were synthesized from different reagents (Ni(II), Co(II) chlorides and 1,8-diaminonaphthalene or the products of a single or double condensation of the latter with salicylaldehyde) and identified and characterized by elemental analysis, powder X-ray diffraction, thermogravimetry, and conductivity methods. The ligand coordination mode and the spatial structure of the complexes were established from the magnetochemisty and spectroscopy (IR, diffuse reflection) data. The dimeric structure of one of the complexes formed due to the chloride bridges was confirmed by EXAFS method.
