| Abstract: | A transition metal-substituted silylacetylene (η5-C5H5)Fe(CO)2SiMe2C]2, FpMe2SiC]2 (I) was synthesized and characterized spectroscopically and structurally. I crystallized in the monoclinic space group P21/n, A = 13.011(3) Å B = 12.912(3) Å, C = 13.175(5) Å, β = 94.95(2). The acetylene linkage is reactive toward Co2(CO)8 to form I. Co2(CO)6 (II) which was also characterized spectroscopically and by single crystal X-ray diffraction. II crystallized in the orthorhombic space group Pbca, A = 17.64(2) Å, B = 14.225(10) Å, C = 24.49(2) Å. |
