  Base-Free and Bisphosphine Ligand Dialkylmanganese(II) Complexes as Precursors for Manganese Metal Deposition

  摘要：

  The solid-state structures and the physical, solution magnetic, solid-state magnetic, and spectroscopic (NMR and UV/vis) properties of a range of oxygen- and nitrogen-free dialkylmanganese(II) complexes are reported, and the solution reactivity of these complexes toward H-2 and ZnEt2 is described. The compounds investigated are [{Mn(mu-CH2SiMe3)(2)}(infinity)] (1), [{Mn(CH2CMe3)(mu-CH2CMe3)(2)}(2){Mn-(mu-CH2CMe3)(2)Mn}] (2), [Mn(CH2SiMe3)(2)(dmpe)] (3; dmpe = 1,2-bis(dimethylphosphino)ethane), [{Mn(CH2CMe3)(2)(mu-dmpe)}(2)] (4), [{Mn(CH2SiMe3)(mu-CH2SiMe3)(mu-dmpe)] (5), [{Mn(CH2CMe3)(mu-CH2CMe3)}(2)(mu-dmpe)] (6), [{Mn-(CH2SiMe3)(mu-CH2SiMe3)}(2)(mu-dmpm)] (7; dmpm = bis(dimethylphosphino)methane), and [{Mn(CH2CMe3)(mu-CH2CMe3)}(2)(mu-dmpm)] (8). Syntheses for 1-4 have previously been reported, but the solid-state structures and most properties of 2-4 had not been described. Compounds 5 and 6, with a 1:2 dmpe/Mn ratio, were prepared by reaction of 3 and 4 with base-free 1 and 2, respectively. Compounds 7 and 8 were accessed by reaction of 1 and 2 with 0.5 equiv or more of dmpm per manganese atom. An X-ray structure of 2 revealed a tetrametallic structure with two terminal and six bridging alkyl groups. In the solid state, bisphosphine-coordinated 3-8 adopted three distinct structural types: (a) monometallic [LMnR2], (b) dimetallic [R2Mn(mu-L)(2)MnR2], and (c) dimetallic [{RMn(mu-R)}(2)(mu-L)] (L = dmpe, dmpm). Compound 3 exhibited particularly desirable properties for an ALD or CVD precursor, melting at 62-63 degrees C, subliming at 60 degrees C (5 mTorr), and showing negligible decomposition after 24 h at 120 degrees C. Comparison of variable-temperature solution and solid-state magnetic data provided insight into the solution structures of 2-8. Solution reactions of 1-8 with H-2 yielded manganese metal, demonstrating the thermodynamic feasibility of the key reaction steps required for manganese(II) dialkyl complexes to serve, in combination with H-2 as precursors for metal ALD or pulsed CVD. In contrast, the solution reactions of 1-8 with ZnEt2 yielded a zinc manganese alloy with an approximate 1:1 Zn/Mn ratio.
