Heteroleptic manganese compounds, [Mn(tmhd)(TMEDA)Cl] (1), [Mn(tmhd)(dmamp)] (2), Mn(tmhd)(edpa)(μ-THF) (3), [Mn(dmampea)(NEt)] (4), and Mn(dmampea)(Pr-MeAMD) (5), were synthesized and characterized. Compound 5 was a volatile liquid. Structural analysis revealed that 1-4 were dimers. Compounds 1 and 3, 2, and 4 had distorted octahedral, distorted trigonal-bipyramidal, and distorted tetrahedral geometries around the Mn centers, respectively. Based on thermogravimetric analysis, the residues of 2 and 3 were expected to be MnO and MnO, respectively. According to thermogravimetric analysis, 4 showed a higher residual value, whereas 5 exhibited a lower value than those expected for manganese nitrides.
合成并表征了杂配锰化合物[Mn(tmhd)(TMEDA)Cl] (1)、[Mn(tmhd)(dmamp)] (2)、Mn(tmhd)(edpa)(μ-THF) (3)、[Mn(dmampea)(NEt)] (4)和Mn(dmampea)(Pr-MeAMD) (5)。化合物5是挥发性液体。结构分析表明1-4为二聚体。化合物1和3、2和4在Mn中心周围分别具有扭曲的八面体、扭曲的三角双锥和扭曲的四面体几何构型。基于热重分析，预计2和3的残渣分别为MnO和MnO。根据热重分析，4显示出较高的残留值，而5的残留值低于氮化锰预期的值。
