    Notes: Reaction of acetyl chloride with [Pt(Cl2Fc)(CH3)(bipy)], where Cl2Fc and bipy are 1,1′-dichloroferrocen-2-yl and 2,2′-bipyridine, respectively, results in the trans oxidative-addition of the acetyl chloride to the PtII precursor to give the PtIV title compound, i.e. [Pt(CH3)(C2H3O)(C10H7Cl2Fe)Cl(C10H8N2)]. The three Pt—C bonds in the title compound are in a fac-configuration and range in length from 2.018 (12) to 2.079 (11) Å. The chloro substituents of the ferrocenyl unit are in an eclipsed conformation.

    Notes: Reaction of 2-lithio-1,1′-dichloroferrocene (LiCl2Fc) with [PtI(CH3)3(bipy)], where bipy is 2,2′-bipyridine, results in the formation of fac-[Pt(CH3)3(Cl2Fc)(bipy)], i.e. fac-[Pt(CH3)3(C10H7Cl2Fe)(C10H8N2)]. The three methyl groups of the octahedral metal complex are in the fac configuration, with Pt—C bond lengths of 2.072 (11), 2.082 (11) and 2.092 (11) Å, together with a Pt—C(Cl2Fc) distance of 2.146 (11) Å. In one of the two independent molecules in the asymmetric unit, the C atoms of the cyclopentadienyl rings are in an eclipsed conformation, while in the other, they are staggered by 26.7°.

    Notes: Reaction of [Zn(hfac)2]·2H2O with L1, where hfac and L1 are hexafluoroacetylacetonate and 2,6-bis[1-(4-tert-butylphenylimino)ethyl]pyridine, respectively, results in the formation of [Zn(L1)2][Zn(hfac)3]2, i.e. [Zn(C29H35N3)2][Zn(C5HF6O2)3]2·0.5C4H10O. In the cation, the two L1 ligands act as mer-terdentate ligands. Reaction of [Zn(hfac)2]·2H2O with 2,2′:6′,2′′-terpyridine (terpy) results in the formation of [Zn(terpy)2](hfac)2.

    Notes: A series of rhenium(I) tricarbonyl halide complexes of pyridyl mono- and di-carboxamides and -thioamides has been studied by dynamic NMR techniques. Oxygen coordination to ReI of the carboxamide ligand reduced the energy barrier to C-N rotation by 2-13 kJ mol-1 whereas sulfur-ReI coordination of the thioamide ligands led to a reduction of 28-33 kJ mol-1. In the pyridyl dicarboxamide and -dithioamide metal chelate complexes metallotropic shifts occur between the three donor atoms, O, N, O or S, N, S, energies [ΔG

    The Crystal Structure of (1, 1′-ferrocenediyl)diphenylsilane (1976)
    New York, NY : Wiley-Blackwell

    Topics: Chemistry and Pharmacology
    Notes: The crystal structure of (1,1′-ferrocenediyl)diphenylsilane has been determined from analysis of photographic X-ray data. The crystal system is orthorhombic, a = 14.18(2), b = 12.54(2), c = 9.28(1) Å, space group Pnma with four formula units. The molecule has crystallographic m (Cs) symmetry with atoms Fe and Si lying in the mirror plane, which bisects the two phenyl groups. The planar cyclopentadienyl rings are bridged by a single silicon atom, and are tilted 19.2° with respect to one another. The Fe - C(Cp) distances vary from 2.01(1) to 2.11(1) Å. The bridging angle C(1) - Si - C(1′) is 99.1°, while the Si - C(sp2) bond lengths range from 1.86 to 1.88 Å. The exocyclic C(1) - Si bond makes an angle of 40° with respect to the plane of the cyclopentadienyl ring.
