No full textReflux of a benzene solution of Cp2Mo2Fe2(CO)(7)Te-2 and PhN3 in the presence of air afforded the new compound CP2Mo2O2(mu-Te)(mu-NC6H5) in 33% yield. It was characterised by IR and H-1 and Te-125 NMR. spectroscopy. Crystallographic analysis established its structure. The structure can be described as consisting of a CpMo-MoCp unit, bridged by a mu-Te atom and an imido ligand. Also bonded lo each Mo atom is a terminally bonded oxo group

No full textOrganic and organometallic compounds were prepared, and their suitability as materials for thin films and for halocarbon sensors were characterized. Thin films were prepared by spin-on-coating and by sublimation. As organic materials crown ethers, polycrown ethers and polysiloxanes were used. 64 different metal complexes (metal = Mn, Fe, Ni, Co, Pt, Pd, Ag, Cu, Zn, Mg, La) with crown ethers acetylacetone and phthalocyanine as ligands were included in the study together with Pd-dibenyzlidenacetone and ferrocene. It is demonstrated that by variation of metal and ligands the sensitive time, sensitivity and selectivity can be strongly modifiedSIGLEAvailable from TIB Hannover: F93B1313+a / FIZ - Fachinformationszzentrum Karlsruhe / TIB - Technische InformationsbibliothekBundesministerium fuer Forschung und Technologie (BMFT), Bonn (Germany)DEGerman

Synthesis, optical nonlinearity and crystal structure of a novel mixed-chalcogen, thiolato-bridged complex [(eta(5)-C5H5)(2)Mo-2(mu-S)(mu-Te)(mu-SPh)(2)]
No full textA novel dimolybdenum complex in which the metal atoms are bridged by two different chalcogens and two thiolato ligands has been synthesised and structurally characterised. This complex shows a large third-order optical nonlinearity as measured by degenerate four-wave mixing with picosecond excitation at 532 nm. A hyperpolarisability (gamma) of 1.2 x 10(-30) esu has been obtained. The structure of the complex was established by the single-crystal X-ray diffraction method. It consists of a Mo-Mo unit, which is bridged by one S, one Te and two (SPh) groups. Each Mo atom also has a (eta(5)-C5H5) group attached to it. (C) 2000 Elsevier Science S.A.
