    A Very-High-Spin Molecule: Preparation, Characterization and Magnetic Properties of an FeIII-GdIII Complex with an S = 12/2 Ground State (1998)

    Notes: The tripodal ligand tris[4-(2-hydroxy-3-methoxyphenyl)-3-aza-3-buten]amine (H3vantren) offers two coordination sites, an inner N4O3 one and an outer O6 one. Therefore, it can successively encapsulate two different metal ions, a 3d(III) ion in the N4O3 site, and a 4f(III) ion in the O6 site. This general route to homo- and heterodinuclear complexes has been exploited for the preparation of the vantrenFeGd(NO3)3 · 2 H2O complex (2), featuring a high-spin iron centre. This compound has been characterized by chemical analysis and mass spectrometry (FAB+). Its magnetic properties have been investigated and show that the (Fe,Gd) pair (2) exhibits a ferromagnetic interaction of low intensity [J = 0.50(5) cm-1]. The resulting S = 12/2 ground state is, most probably, the highest spin ground state that can be expected for a dinuclear complex.

    Hybridization mapping of Trypanosoma cruzi chromosomes III and IV (1998)

    Notes: As part of the Trypanosoma Genome Initiative launched by the World Health Organization (WHO), a physical clone map of Trypanosoma cruzi chromosomes III and IV was generated to facilitate both DNA sequence analysis of the parasite's genome and the investigation of chromosome organization. Apart from a few genetic markers, anonymous cosmids were taken from chromosomal sublibraries and individually hybridized to filter arrays of the relevant cosmid library. The probe order was determined from the hybridization fingerprint results and used to define a fitting clone order, with few gaps remaining. The results were independently verified by hybridizations to a bacterial artificial chromosome (BAC) library and, in case of chromosome III, restriction mapping. For gap closure, additional experiments on a total cosmid library were carried out. The possible tiling paths consist of 26 clones for chromosome III (610 kbp) and 28 clones for chromosome IV (680 kbp).

    Sur les conditions de formation des complexes des chloroalkylgallium (ClnR3-nGa) avec diverses bases de Lewis (R2O, R2S, R3N et R3P): étude par spectroscopie de RMN (1H) (1973)

    Description / Table of Contents: From an NMR (1H) study of various systems chloroalkylgallium/Lewis bases, it appears that the four types of gallium compounds (ClnR3-nGa) form adducts with trialkylamines, trialkylphosphines, ethers and sulphides, and that in all cases the 1:1 complex seems to be the only existing one. Its stability mainly depends on the number of chlorine atoms bound to the gallium and on the nature of the donor site.
    Notes: Une étude des conditions de formation des complexes résultant de l'addition des bases de Lewis usuelles (R2O, R2S, R3Net R3P) sur les chloroalkylgallium (ClnR3-nGa) a été réalisée à l'aide de la spectroscopie de RMN.Il apparaǐt que les seuls composés à se former à la température ambiante sont des complexes mettant en jeu 1 mole de base et 1 mole d'acide. Leur stabilité est gouvernée par le nombre d'atomes de chlore fixés sur le gallium et par la nature de l'atome donneur.
