Resumo
A salt elimination reaction between [YCl3(THF)(3.5)] and 1 or 2 equiv. of Tl(Tp(Ms*)) [Tp(Ms*) = HB(3-mesitylpyrazolyl)2(5-mesitylpyrazolyl)(-)] leads in both cases to single metathesis, giving a mixture of the mono-Tp(Ms*) complex [YCl3(Tp(Ms*))Tl] (1) and another complex, [YCl2(Tp(Ms* *))] (2) [Tp(Ms* *) = HB(3-mesitylpyrazolyl)(5-mesitylpyrazolyl)(2)(-)], that results from the transfer of a second mesityl group to the 5-position of the pyrazolyl ring. The solid-state structure of 1 shows a unique ate dimeric structure with the TV cations coordinated by two mu(2)- and two mu(3)-bridging Cl atoms as well as two eta(3)-mesityl ligands.
