New heteroligand cobalt(II), iron(II), and manganese(II) complexes of the M(3,6-SQ)2L type bearing 3,6-di-tert-butyl-o-benzosemiquinonato ligands (3,6-SQ) and 2,2'-biquinoline or 1,4-di-tert-butyl-1,4-diazabutadiene-1,3 as neutral ligands (L) have been synthesized and characterized. It was shown on the basis of the magnetic susceptibility measurements and spectroscopic studies that all complexes contain metal(II) ions in the high-spin state and two radical-anionic o-semiquinonato ligands. It was found in the result of analysis of magnetic susceptibility temperature dependence by magnetic coupling parameters modeling that the antiferromagnetic ligand-ligand coupling takes place in the cobalt(II) and iron(II) complexes, while antiferromagnetic metal-ligand interactions dominate in the manganese(II) complexes.

双邻苯并半醌钴 (II)、铁 (II) 和锰 (II) 与 2,2'-双喹啉和 1,4-二叔丁基-1,4-二氮杂丁二烯配合物的磁性

M(3,6-SQ)2L 型的新型杂配体钴 (II)、铁 (II) 和锰 (II) 配合物带有 3,6-二叔丁基-邻苯并半醌配体 (3,6- SQ) 和 2,2'-biquinoline 或 1,4-di-tert-butyl-1,4-diazabutadiene-1,3 作为中性配体 (L) 已被合成和表征。磁化率测量和光谱研究表明，所有配合物都含有高自旋状态的金属 (II) 离子和两个自由基阴离子邻半醌配体。通过磁耦合参数建模分析磁化率温度依赖性的结果发现，反铁磁配体-配体耦合发生在钴(II)和铁(II)配合物中，而反铁磁金属-配体相互作用在锰中占主导地位（二）配合物。
