The morphology of sodium partially and totally neutralized carboxytelechelic ionomers has been characterized by small-angle X-ray scattering showing that the aggregates grow as more end chains are neutralized while keeping the electron density constant, in agreemeent with the multiplet model.

The nearly planar title molecules are linked by a pairs of N—H
O interactions into an inverson dimer. The dimers are connectec by weak HCl interactions into a two-dimensional hydrogen-bonded polymer and stacked along the b axis, connected by weak π–π interactions. An in silico evaluation of the title compound with an topoisomerase enzyme was performed and several intermolecular interactions can be assigned.

In the title compound, C9H7FN4OS, the molecules are almost planar, with an r.m.s. deviation of 0.047 (3) Å from the mean plane defined by the non-H atoms and a maximum deviation of 0.123 (2) Å for the amine N atom. The torsion angle for the N—N—C—S unit is 176.57 (19)°. In the crystal, molecules are linked into inversion dimers via pairs of N—HF hydrogen bonds and, additionally, through N—HO and N—HS hydrogen bonds, building a two-dimensional hydrogen-bond network parallel to the (103) plane. An intramolecular N—HO interaction is also observed.

The title molecule, C5H5N5O3S, is approximately planar, with a maximum deviation from the mean plane through the non-H atoms of 0.182 (3) Å for the amine N atom. In the crystal, molecules are connected via N—HO and N—HS interactions, building a three-dimensional hydrogen-bonded network. Additionally, a weak intramolecular N—HO hydrogen bond is observed.

The additional absorbance spectra of samples exposed to ultraviolet light show that the silver colloid formation is possible only in samples that exhibit SAXS curves characteristic of well defined particles dispersed in glass.
