摘要：
2,6-Diformyl-4-tert-butylphenol bis(8-quinolylhydrazone) and its transition metal complexes of the compositions [Cu2(H2L)Cl]Cl2, [Ni2(H2L)Cl3], and [Mn2(H2L)Cl3], where H2L is the monodeprotonated form of the hydrazone, are prepared. The conformations of the bis-hydrazone, geometries of the complexes, and parameters of exchange coupling between the ferromagnetic centers are evaluated by quantum-chemical calculations. The calculation results are compared with the results of the physicochemical study of the compounds. Factors affecting the stability of various forms of the ligand and complexes are discussed.
