The gallium−chalcogen heterocubanes
[Cp*Ga(μ3-E)]4, E = S (1)
and Se (2), and
[Cp†Ga(μ3-Se)]4 (3) have been synthesized by
dehalosilylation
reactions between E(SiMe3)2 (E = S, Se) and
RGaCl2, R
= Cp* (C5Me5) and Cp†
(C5Me4Et), and are
characterized
by elemental analyses, NMR spectroscopy, and mass
spectrometry. The use of compounds 1 and 2
as single-source MOCVD precursors for the low-temperature
growth of Ga2E3 films at 290−310 °C is
described. The
as-deposited films were amorphous; however, upon
thermal annealing (500 °C) the films crystallized to the
thermodynamic cubic phases, while the corresponding
tellurium analog decomposed in the solid state at 220
°C forming a gallium-rich product.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
