Formation of the linear chain ruthenium and osmium carbonyls by successive linkage of mononuclear [M(CO)4Cl2] units and by opening trinuclear clusters [M3(CO)12] and [FeM2(CO)12] (M = Ru, Os) with chlorine gas have been studied by computational DFT methods. Energetically the formation of dinuclear [M2(CO)8Cl2] from [M(CO)4Cl2] units is the most demanding step. The following chain growth by adding new

Transientinfraredspectroscopy is used to study coordinatively unsaturated Ru(CO)sub x} products formed by excimerlaserphotolysis of gas-phase Ru(CO)sub 5}. Both RU(CO)sub 4} and Ru(CO)sub 3} are photoproducts of 248- and 351-nm irradiation of Ru(CO)sub 5}. This is the first report of direct observation of unsaturated Ru(CO)sub x} species. Unlike the well-known Fe(CO)sub 4} fragment, the
The crystal and molecular structure of [Ru(CO)4}n] has been determined solely from X-ray powder diffraction data using standard laboratory equipment and refined with a (modified) Rietveld procedure. The compound crystallizes in the orthorhombic space group Ibam, with a = 14.147(4), b = 7.060(2) and c = 5.720(1) angstrom, Z = 4; the final refinement (19 variables) converged to R(p') R(wp) and R(Bragg) of 0.077, 0.102 and 0.025, respectively, for 4001 data collected at room temperature in the 5-85-degrees (2theta) range. The structure, which consists of a polymeric stack of staggered trans-D4h Ru(CO)4 fragments separated by a Ru-Ru contact of 2.860(1) angstrom, is the first polymeric binary metal carbonyl compound so far characterized. Strain and particle-size broadening effects have been observed, and the microstructural properties of the compound are discussed.
