Abstract

{Ru3(CO)9{mu-3-P[C6H5Cr(CO)3]}[mu-3-C6H4Cr(CO)3] (2) is prepared by reacting Ru3(CO)12 with PhP[C6H5Cr-(CO)3]2. The crystal structure shows the aryne moiety, C6H4Cr(CO)3, eta-2 bound to three Ru atoms that are part of a Ru3P butterfly arrangement. A Cr –> Ru bond is proposed. The P atom is bound to the C6H5Cr(CO)3 moiety and three Ru atoms. In contrast, the product of the thermal decomposition of Ru3(CO)11PPh2[C6H5Cr(CO)3] is the mu-3-eta-2-benzyne complex Ru3(CO)7(mu-3-eta-2-C6H4){mu-PPh-[C6H5Cr(CO)3]}2 (3). Crystals of 2 are monoclinic, with a = 16.918 (2) angstrom
