Trimetallaborides as starting points for the syntheses of large metal-rich molecular borides and clusters
Treatment of an anionic dimanganaborylene complex ([{Cp(CO)(2)Mn}(2)B](–)) with coinage metal cations stabilized by a very weakly coordinating Lewis base (SMe(2)) led to the coordination of the incoming metal and subsequent displacement of dimethylsulfide in the formation of hexametalladiborides fea...

description | Treatment of an anionic dimanganaborylene complex ([{Cp(CO)(2)Mn}(2)B](–)) with coinage metal cations stabilized by a very weakly coordinating Lewis base (SMe(2)) led to the coordination of the incoming metal and subsequent displacement of dimethylsulfide in the formation of hexametalladiborides featuring planar four-membered M(2)B(2) cores (M = Cu, Au) comparable to transition metal clusters constructed around four-membered rings composed solely of coinage metals. The analogies between compounds consisting of B(2)M(2) units and M(4) (M = Cu, Au) units speak to the often overlooked metalloid nature of boron. Treatment of one of these compounds (M = Cu) with a Lewis-basic metal fragment (Pt(PCy(3))(2)) led to the formation of a tetrametallaboride featuring two manganese, one copper and one platinum atom, all bound to boron in a geometry not yet seen for this kind of compound. Computational examination suggests that this geometry is the result of d(10)–d(10) dispersion interactions between the copper and platinum fragments. |
