Five-coordinate gallium and aluminium dihydrides, H2Ga[N(CH2CH2NMe2)2] (1) and H2Al[N(CH2CH2NMe2)2] (3), were synthesized and found to be volatile and thermally stable. 1 and 3 reacted with H3Ga(NMe3) and H3Al(NMe3), respectively, to form H2Ga[N(CH2CH2NMe2)2]GaH3 (2) and H2Al[N(CH2CH2NMe2)2]AlH3 (4), in which the amido nitrogen bridged between the MH2 and MH3 groups (M = Ga or Al). A mixed metal complex, H2Al[N(CH2CH2NMe2)2]GaH3 (5) was obtained from the reaction of 1 with H3Al(NMe3) or 3 with H3Ga(NMe3), and a crystal consisting of a mixture of 5 and 2 was structurally characterized. The five-coordinate chloro derivative, Cl2Ga[N(CH2CH2NMe2)2] (6), was synthesized and characterized.

Bis(2-dimethylaminoethyl)amido gallane, H2GaN(CH2CH2NMe2)2, that melts at 27 degrees C and remains stable upon heating at 55 degrees C for two days, was synthesized either from the reaction of the quinuclidine adduct of monochlorogallane with the lithium salt of the corresponding amine, or from the reaction of trimethylaminegallane and the amine; the latter affords an unusual co-product with both

The synthesis and characterization of complexes with a tridentate amido-diamine ligand N(CH2CH2NMe2)(2), [ClZnN(CH2CH2NMe2)(2)](2) (1), [EtZnN(CH(2)CH(2)NMel)(2)](2) (2), JZn[N(CH(2)CH2NMe(2))(2)](2)}(2) (3) and [(Bu2NZnN)-Bu-t(CH2CH2NMe2)(2)](2) (4), are described. Compounds 1 (57% yield) and 2 (49% yield) were obtained from the reactions of ZnCl2 with 1 equiv. of LiN(CH2CH2NMe2)(2) and ZnEt2 with excess HN(CH2CH2NMe2)(2), respectively. Compounds 3 (52% yield) and 4 (75% yield) were isolated from the reactions of [Zn((NBu2)-Bu-i)(2)](2) With HN(CH2CH2NMe2)(2) in 1:4 and 1:2 molar ratios, respectively. Mass spectral data and NMR analyses suggested that all four compounds were dimeric. The solid-state structures of compounds 2 and 3 were determined via X-ray crystallography. Both compounds were centrosymmetric containing a four-membered Zn2N2 ring with bridging amido ligands. In both structures, one NMe2 group in each bridging ligand bonded to a Zn center forming a five-membered ring. The ethyl groups in 2 and the second -N(CH2CH2NMe2)(2) ligand in 3 occupied the terminal positions. (c) 2005 Elsevier Ltd. All rights reserved.

Methods for forming a Li-containing film, islet or cluster on a substrate comprise the steps of introducing a vapor of a silicon-free lithium precursor into a reactor and depositing at least part of the silicon-free lithium precursor onto the substrate to form the Li-containing film, islet or cluster using a vapor deposition method.
