Ca 3 (thd) 6 ] (thd ) 2,2,6,6-tetramethyl-3,5-heptanedionato) dissolved in hexane and in the presence of tetraethylenepentamine (tetraen) crystallizes as a 1:1 [Ca(thd) 2 (tetraen)] adduct complex in the orthorhombic Pccn space group with a ) 10.874(2) Å, b ) 15.480(3) Å, c ) 20.866(4) Å, and Z ) 4. The molecule is monomeric with an 8-coordinated calcium atom. The adduct complex volatilized at lower temperature than the nonadducted complex. [Ca-(thd) 2 (tetraen)] can be utilized as a precursor in growth CaS thin films by the atomic layer epitaxy method. The growth rate with [Ca(thd) 2 (tetraen)] is lower (0.43 Å/cycle) than that with [Ca 3 (thd) 6 ] (0.50 Å/cycle).

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.
