  摘要：

  已知的单核钴(II)和镍(II)配合物 [H2N(C5H3N)N(H)C(Me)=NH]M(OOCBut)2、[(NH2)2C6H2Me2]3M(OOCBut)2 以及新化合物 L2M(OOCBut)2 (L = (2-NH2)C5H3N, (2-NH2)(6-Me)C5H3N) 和 [(2,6-NH2)2C5H3N]2Ni(OOCBut)2 的热稳定性和固态热分解通过差示扫描量热法和热重分析进行了研究。开发了这些配合物的有效合成方法。单核配合物在热上相当稳定。配合物的热稳定性取决于配体的性质，并呈现下降趋势：(2,6-NH2)2C5H3N > H2N(C5H3N)NHC(Me)=NH > (NH2)2C6H2Me2 > (2-NH2)C5H3N > (2-NH2)(6-Me)C5H3N。镍(II)配合物的热稳定性高于相关的钴(II)配合物。钴和镍的己酸酯的热解（<500 °C）是一个破坏性的过程。分解产物的相组成由金属的性质和配位配体决定。

  Formation of amidine ligands in coordination spheres of Co^IIand Ni^IIatoms

  摘要：

  Reactions of polynuclear cobalt and nickel pivalates with amines in MeCN afforded compounds containing the amidine ligands (MeC(NHR)=NH). The reactions with 2,6-diaminopyridine yielded the Ni(Me3CCOO)(2){H2N(C5H3N)NHC(Me)=NH}, Co-2(Me3CCOO)(4){H2N(C5H3N)NHC(Me)=NH},Co(Me3CCOO)(2){H2N(C5H3N)NHC(Me)=NH} complexes and the solvate of the latter with Me3CCOH and C6H6. The reaction with S-(-)-alpha-methylbenzylamine gave rise to the ionic chiral compound with composition [PhCH(Me)NHC(Me)NH2](+)[Co-2(Me3CCOO)(5)](-) as a diastereomeric salt. According to the results of X-ray diffraction analysis, the asymmetric carbon atom in the cation and the asymmetric cobalt atom in the binuclear anion of this salt have the S absolute configuration.* The Compounds were characterized by elemental analysis data and the results of IR and electronic spectroscopy. Their structures were established by X-ray diffraction analysis. The chiroptical properties of the ionic compound in solution were studied by circular dichroism spectroscopy.
