Synthesis of heteroleptic [Sr(ddemap)(tmhd)]₂ and its use in atomic layer deposition of low carbon SrO thin films.

ABSTRACT: New strontium heteroleptic complexes were synthesized by the substitution reaction of the bis(trimethylsilyl)amide of Sr(btsa)₂·2DME with aminoalkoxide and β-diketonate ligands (btsa = bis(trimethylsilyl)amide, DME = 1,2-dimethoxyethane). Three compounds, [Sr(ddemap)(tmhd)]₂ (1), [Sr(ddemmp)(tmhd)] (2), and [Sr(ddemamb)(tmhd)]₂ (3), were obtained as precursors for SrO growth (ddemap = 1-(dimethylamino)-5-((2-(dimethylamino)ethyl)(methyl)amino)pentan-3-ol, ddemmp = 1-(dimethylamino)-5-((2-(dimethylamino)ethyl)(methyl)amino)-3-methylpentan-3-ol, ddemamb = 1-(dimethylamino)-2-(((2-(dimethylamino)ethyl)(methyl)amino)methyl)butan-2-ol). In single crystal X-ray crystallography, complex 1 showed dimeric structure with µ₂-O bonds of ddemap ligand. Comple
