Notizen:
Reaction of a 1:2 mixture of Y[N(SiMe3)2]3 and Ba[N(SiMe3)2]2 with tBuOH (8 mol equivalents) in Et2O at 25°C yields YBa2(OtBu)7(tBuOH), which has a triangular structure with two μ3-OtBu and three μ2-OtBu ligands, one terminal OtBu on Y and on one Ba, and one terminal tBuOH on the second Ba. All metals are thus five-coordinate. The crystal structure is comprised of chains of triangles of triangles held together by hydrogen bonds from tBuOH of one YBa2 unit to the terminal OtBu on Ba of the next YBa2 unit. This serves as support for the idea that, in certain cases, the heterometallic alkoxide product from alcoholysis of a mixture of two metal complexes can faithfully duplicate the global solution metal stoichiometry.
