Heteroleptic manganese compounds as potential precursors for manganese based thin films and nanomaterials.

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.
