Highly soluble and chemically unstable bimetallic complex Ba2Sn2(thd)4(OiPr)8 (2) can be obtained with quantitative yield by interaction of Sn(OiPr)4 (obtained by desolvation of the commercially available Sn(OiPr)4(iPrOH)) with 1 eq. of Ba(thd)2 produced in situ in toluene. Microhydrolysis or solvolysis of this complex by parent alcohol results in its transformation into a mixture of easier isolable bimetallic solvates, Ba2Sn(thd)4(OiPr)4(iPrOH)2 (3) and BaSn2(thd)2(OiPr)8(iPrOH)2 (1) that have been isolated and structurally characterized. All three complexes reveal considerable volatility according to TGA data, making the studied beta-diketonate alkoxide system interesting for further evaluation for production of BaSnO3 thin films by MOCVD technique. Thermal decomposition of 1 and 3 provides mixtures of oxides dominated by BaSnO3, while that of 2 offers pure perovskite BaSnO3 phase.
Graphical abstractBimetalic alkoxide beta-diketonate barium–tin complexes are easily obtained by interaction of in situ generated barium 2,2,6,6-tetramethylheptane-dionate with tin(IV) isopropoxide.Figure optionsDownload full-size imageDownload as PowerPoint slide
