In article number 1605448, Garikoitz Beobide, Oscar Castillo, and co‐workers report the preparation of a series of metal‐organic gels (MOGs) and aerogels (MOAs) based on the assembly of 1D coordination polymer nanofibers based on the dithiooxamidato ligand. Properties including porosity, chemical inertness, mechanical robustness, and stimuli‐responsive electrical conductivity are achieved in a single material. The strength of the M–S bond confers an unusual chemical resistance, withstanding exposure to acids, alkalis, and mild oxidizing/reducing chemicals. MOAs are obtained by supercritical drying of MOGs, providing ultralight porous materials that present a plastic/brittle behavior depending on the nanofiber aspect ratio.
