Molecular design approach to single-source precursors of perovskite stannate materials

Seisenbaeva, Gulaim; Topel, Seda Demirel; Kessler, Vadim


Highly soluble and chemically unstable bimetallic complex Ba2Sn2(thd)(4)((OPr)-Pr-i)(8) (2) can be obtained with quantitative yield by interaction of Sn((OPr)-Pr-i)(4) (obtained by desolvation of the commercially available Sn((OPr)-Pr-i)(4)((PrOH)-Pr-i)) 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)((OPr)-Pr-i)(4)((PrOH)-Pr-i)(2) (3) and BaSn2(thd)(2)((OPr)-Pr-i)(8)((PrOH)-Pr-i)(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. (C) 2014 Elsevier Ltd. All rights reserved.
