    Notes: [Auszug] As boron trifluoride complexes are systems for which the activation energies of ionic migration are very similar to those of viscous flow3'4, it is likely that similar configurational changes occur in the two processes and that ionic mobility at various temperatures will be proportional to the ...

    Notes: [Auszug] RHENIUM(IV), with an electronic configuration 5d3, usually shows a magnetic moment corresponding to three unpaired electrons in its octahedral halocomplexes of the type M2ReX6 (ref. 1). In contrast, the magnetic moment of rhenium(IV) chloride appears to be anomalously low2, suggesting the presence ...

    Synthesis of Transition Metal Complexes of the Unknown Chelate, Dithioacetylacetone (1966)

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] Recently, it has become apparent that bidentate sulphur chelates confer highly novel stereochemical, magnetic and spectral properties on transition metal ions which are due, in part, to the ease with which sulphur can participate in 7r-bonding with the central metal ion. We have been concerned, in ...

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] IN a recent communication1 we directed attention to the fact that compounds involving polynuclear metal clusters are not necessarily diamagnetic, and that para-magnetism can often be of diagnostic value for detecting the presence of metal-metal bonding. If a core is constituted of an odd number of ...

    Notes: [Auszug] Contrary to their above statement, however, one of the several logical developments of our scheme does, in fact, predict species which are members of the Ti3(a;+])O4a; (OEt)4(aH.3) series suggested by the workers at Birkbeck College, namely : Ti3(OJR)12 +Ti3(O#)6(OH)6 -〉Ti6O4(0R)16 +2ROH +2H20 ...

    Notes: [Auszug] Structure I has been widely accepted2 as the basis on which to interpret the chemistry of titanium (IV) alkoxides, and, in particular, the group working at Birkbeck College3 have stressed this arrangement when discussing the hydrolysis of these compounds. In fact, they have claimed that the ...

    Association of Titanium (IV) Alkoxides in Benzene (1963)

    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] While it is not unknown for a structural entity in the solid state to differ from that present in solution, it now becomes important to extend previous cryoscopic measurements in benzene12 to higher concentrations to establish whether the degree of association of titanium (IV) n -alkoxides can, in ...

    Oxides of Praseodymium (1950)

    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] Since Pr2O3 is derived from the lower of the two valence states of praseodymium, it might be expected that the potential quadrivalency (on energetic grounds quadrivalency appears more likely than pentavalency) of this metal will favour the formation of a non-stoichiometric phase with a range of ...

    Eclipse Cycles and Eclipses at Stonehenge (1967)

    ISSN: 1476-4687
    Source: Nature Archives 1869 - 2009
    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] Was Stonehenge used to predict eclipses? Previous claims have assumed a high degree of sophistication on the part of the builders of Stonehenge, and that the number of Aubrey holes (56) is particularly significant. It may be that neither assumption is justified or necessary, and that if the ...
