Abstract

Three new molecular zinc compounds were prepared by nonaqueous reactions of Zn[N(SiMe3)(2)](2) and ZnEt2 with trimethylsilylesters of phosphoric acid, OP(OSiMe3)(3) and OP(OSiMe3)(2)(OH). Single-crystal Xray diffraction analyses of crystalline products revealed molecular structures of two mononuclear complexes [ZnX2OP(OSiMe3)(3)] (X = N(SiMe3)(2) (1), hfacac = hexafluoroacetylacetonate, (2)) and one dinuclear zinc phosphate [(Zn{(py)N(SiMe3)(2)}{mu(2)-O2P(OSiMe3)(2)})(2)] (3). Compound 1 is only the second structurally characterized adduct of zinc bisamide with an oxygen donor and a three-coordinate Zn atom. The cyclic inorganic core {Zn(mu(2)-O2PO2)}(2) in 3 is a model for the most common single four-ring (S4R) building unit of open-framework zinc phosphates. The molecule of 3 possesses reactive amide and tri-methylsiloxy groups that can be employed in further studies on the formation of extended structures by condensation reactions. Spectroscopic properties and thermal behavior of the molecular products were examined. Compounds 1 and 3 were converted to alpha-Zn2P2O7 by calcination. (C) 2013 Elsevier B. V. All rights reserved.
