    No full text
    The novel by Puerto Rican author Piri Thomas is analyzed on the background of Latino migratory literature and its quest for assertion within the North-American multiracial context. A close analysis of the structure of the novel and of its characters stands at the basis of the stud

    Crystal of [Ir4Br(CO)11] (PPh4) are orthorhombic, space group P212121, with a 13.276(3), b 18.347(4), c 16.041(4) Å. The structure has been elucidated by the analysis of 2876 observed intensities recorded on an automatic diffractometer, and refined by the least-squares method to R 0.043. The anion contains a tetrahedral cluster of iridium atoms (mean IrIr 2.710 Å). The carbonyl arrangement differs from that of the parent Ir4(CO)12, and is similar to that known for Co4(CO)12 and Rh4(CO)12, with one terminal CO group in the basal M3(CO)9 moiety replaced by the bromide ligand; two of the bridging CO groups become markedly assymetric
