Sumario:Heteroleptic manganese compounds, [Mn(tmhd)(TMEDA)Cl](2) (1), [Mn(tmhd)(dmamp)](2) (2), Mn(2)(tmhd)(2)(edpa)(2)(μ-THF) (3), [Mn(dmampea)(NEt(2))](2) (4), and Mn(dmampea)((i)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 Mn(3)O(4), respectively. According to thermogravimetric analysis, 4 showed a higher residual value, whereas 5 exhibited a lower value than those expected for manganese nitrides.
