    Notes: [Auszug] Bis(salicylaldehydato)copper(II) had unit cell dimensions: a =8.77, 6 = 6.21, c= 12.33 A, =117.4. The structure was solved by three-dimensional Fourier and Patterson methods and refined by the diagonal least -squares technique. There are two centro-symmetric (C7H5O2)2Cu groups in the unit cell, the ...

    Notes: [Auszug] Martin and Waterman extended their observations to the dissolved state and showed that the dimeric structure persisted in dioxane solution, arguments from the magnetic properties being supported by cryoscopic measurements of molecular weight and the appearance of an absorption band about 375 m[jL5. ...

    Notes: [Auszug] The resistance of planar complexes of divalent nickel, palladium and platinum to further co-ordination derives from the effect of the ligand field in so raising the energy of the dx*-y* orbital, which points directly at the ligands, that it remains unoccupied; the consequent pairing of ...

    Notes: [Auszug] The original attribution of structure I to these adducts was essentially intuitive, and as their low stability makes isolation improbable, a definitive structure determination seems unattainable. We believe, however, that the weight of available evidence strongly favours structure (I). (1) The ...

    Notes: [Auszug] We have prepared the anhydrous compound from the dihydrate both by vacuum sublimation and by azeotropic drying of toluene solutions, the latter method providing a particularly convenient means of obtaining water-free solutions. Cryoscopic molecular weight determinations on solutions of the ...

    Notes: [Auszug] In a recent communication, King, Koros and Nelson5 show that the equilibrium constants for the reaction: CoX2JS2 + 2B ^ CoX2£4 increase in the order X = I Br 01 NCO NCS (B = pyridine) and that the difference between thiocya-nate and the halogens is essentially due to the entropy term. ...

    Notes: [Auszug] THE determination by Bullen, Pauling, and JL Mason1 of the crystal structure of tas-acetyl-acetonato-nickel(II) showed that this green, paramagnetic compound, long regarded as an example of tetrahedrally 4: co-ordinated nickel(II), was in fact trimeric, each nickel atom being octahedrally 6: ...
