1411. Structure and population of complex ionic species in FeCl[sub]2 aqueous solution by X-ray absorption spectroscopyUroš Luin, Iztok Arčon, Matjaž Valant, 2022, original scientific article Abstract: Technologies for mass production require cheap and abundant materials such as ferrous chloride (FeCl2). The literature survey shows the lack of experimental studies to validate theoretical conclusions related to the population of ionic Fe-species in the aqueous FeCl2 solution. Here, we present an in situ X-ray absorption study of the structure of the ionic species in the FeCl2 aqueous solution at different concentrations (1–4 molL−1) and temperatures (25–80 ◦C). We found that at low temperature and low FeCl2 concentration, the octahedral first coordination sphere around Fe is occupied by one Cl ion at a distance of 2.33 (±0.02) Å and five water molecules at a distance of 2.095 (±0.005) Å. The structure of the ionic complex gradually changes with an increase in temperature and/or concentration. The apical water molecule is substituted by a chlorine ion to yield a neutral Fe[Cl2(H2O)4]0. The observed substitutional mechanism is facilitated by the presence of the intramolecular hydrogen bonds as well as entropic reasons. The transition from the single charged Fe[Cl(H2O)5]+ to the neutral Fe[Cl2(H2O)4]0 causes a significant drop in the solution conductivity, which well correlates with the existing conductivity models.

1412. La recepción de la literatura latinoamericana en Eslovenia en los años 1960-1970 : hacia una lista exhaustiva de entradas bibliográficasBarbara Pregelj, Francisco Tomsich, 2021, original scientific article Abstract: El núcleo de este artículo es una lista de traducciones, reseñas y diferentes tipos de artículos sobre autores latinoamericanos y/o sus obras literarias vertidas al esloveno, publicados entre 1960 y 1970 en esloveno. Dicha lista ha sido compuesta a partir de la base de datos conservada en el Departamento de Literatura de la Academia de Cien-cias de Eslovenia. Estos datos han sido cotejados, a su vez, con los que figuran en Co-biss, el sistema informático de las bibliotecas eslovenas, para los años 60, con el fin de establecer un cierto marco comparativo.La lista de textos relativos a la recepción de la literatura latinoamericana en Eslo-venia es un documento que permite y exige muchos tipos diferentes de lecturas, y en este artículo se bocetan algunas. Una visión retrospectiva, apoyada en datos y estadís-ticas más recientes, nos ha permitido esbozar una respuesta a la cuestión del significa-do de los autores latinoamericanos y la importancia de sus obras en Eslovenia, tanto hace cincuenta años como en la actualidad.
