摘要：

The novel termetallic oxo-methoxo-tert-butoxide Eu3K3TiO2(OBut)(11)(OMe/OH)(HOBut) (1) has been synthesised and structurally and spectroscopically characterised. Its unusual structure features an Eu3K3O fac-octahedron, capped by a distorted K3TiO tetrahedron on the K-3 face. The compound, crystallising in space group P2(1)/n with cell parameters a = 14.44 , b = 23.58 , c = 21.27 and beta = 96.18A degrees, is the result of incomplete metathesis between EuCl3 and potassium and titanium tert-butoxides in combination with deliberate hydrolysis and decomposition. It provides one of few examples of termetallic lanthanide alkoxides, as well as of an alkoxide tert-butyl group decomposing into a methyl group.
