Trispentafluorophenylsilane has been prepared and characterized. The silane has been used to prepare the monohalides, (C6F5)3SiX (X = Cl, Br), as well as the disiloxane, (C6F5)3Si-O-Si(C6F5)3. The silane has also been found to react with the binuclear metal carbonyls Co2(CO)8 and M2(CO)10 (M = Mn, Re) to yield the silyl-metal derivatives. We report the preparation and infrared and mass spectra of these compounds, and their reactivity towards triphenylphosphine.

Theoretical studies indicate the complexes M(CO)n(PS) with bent 1-e/2-e donor PS groups to be unstable for giving the stable M(CO)n−1(PS) with linear 3-e donor PS groups. In addition, only Mn2(CO)8(P2S2) is energetically viable from the Mn(CO)4(PS).

The mass spectra of the following olefin derivatives of metal carbonyls have been investigated: (a) Arene—tungsten tricarbonyl complexes of toluene, p-xylene, and mesitylene; (b) The cycloheptatriene—metal tricarbonyl complexes C7H8M(CO)3 (M = Cr and W); (c) The 1,3,5-cyclooctatriene complex C8H10W(CO)3; (d) The cyclooctatetraene—metal tricarbonyl complexes C8H8M (CO)3 (M = Cr or Fe); (e) The 1,5-cyclooctadiene—metal tetracarbonyl complexes C8H12M(CO)4 (M = Mo or W); (f) The tungsten tetracarbonyl complexes of bicyclo[2,2,1] heptadiene and dicyclopentadiene; (g) The 1,3-cyclohexadiene complexes (C6H8)2M(CO)2 (M = Mo or W); (h) The cycloheptadienol complex (C7H9OH)Fe(CO)3; (i) The methyl vinyl ketone complexes (CH3COCH = CH2)3M (M = Mo or W); (j) A product of composition C12H16Fe(CO)2 obtained from allene dimer and Fe3(CO)12. The following fragmentation processes of particular interest were observed: (a) The facile dehydrogenation of ions containing the π-bonded 1,3,5-cyclooctatriene, 1,5-cyclooctadiene, and 1,3-cyclohexadiene ligands with two adjacent CH2 groups; (b) Elimination of neutral C5H6 fragments from tungsten carbonyl ions containing π-bonded bicyclo[2,2,1] heptadiene or dicyclopentadiene ligands; (c) Facile dehydration of iron carbonyl ions with π-bonded cycloheptadienol.

The crystal and molecular structures have been determined, by single-crystal X-ray methods, for each of the isomorphous set of divalent binuclear metal derivatives of 1,3-diphenyltriazene, abbreviated as dptH, [M(dpt)2]2 where M = Ni, Pd, and Cu. The crystals are composed of discrete molecular units, of composition M2(dpt)4, which have a syn-syn structure analogous to that of copper(II) acetate monohydrate with pairs of closely separated metal atoms held together by the terminal nitrogen atoms of four ligand groups in such a way that the environment of each metal atom is almost square-planar. The interatomic distances between the pairs of metal atoms, 2.395(3), 2563(1), and 2.441(2) Ǻ for the Ni, Pd, and Cu compounds, are strongly suggestive of metal-metal bonding. The two N4-planes are almost parallel but the two sets of coordinating nitrogen atoms are twisted markedly from the eclipsed configuration, the average angle of rotation being about 15°. Crystals of each complex are triclinic with space group P 1. The unit cell parameters in the order of a, b, c, α, β, and γ are 10.335(3), 15.84(1), 13.546(3)& 100.48(5), 94.47(2), 102.57(3)° for Ni2(dpt)4; 10.486(1), 15.791(2), 13.751(1)Ǻ, 99.48(1), 93.61(1), 104.37(1)° for Pd2(dpt)4; 10.373(3), 15.916(5), 13.612(3) Ǻ, 99.51(2), 94.85(3), 102.33(2)° for Cu2(dpt)4. The structure of the nickel complex was solved by the Patterson-Fourier method and the atomic parameters found for this structure were used as the basis of the structure determinations of the isomorphous copper and palladium compounds. All three structures were refined by a block-diagonal least-squares method using 3300 (photographic data) 4065 (counter) and 2753 (counter) independent non-zero terms for the nickel(II), palladium(II) and copper(II) compounds respectively, converging with R values 0.13 (isotropic), 0.056 (anisotropic) and 0.069 (isotropic) respectively.
