First Time

New crown-containing imines of 1-hydroxyanthraquinone with chlorine and fluorine atoms in the anthraquinone nucleus were synthesized. For the first time, the thermal and photochemical stages of synthesis are carried out in the solid state (without a solvent). The features of complexation of new chemosensors with cations of alkaline and alkaline earth metals were studied by spectrophotometry. It is shown that the introduction of halogen atoms in the anthraquinone nucleus leads to a significant spectral response. The obtained compounds are tested as components of test systems for visual determining the presence of alkaline earth metal cations in aqueous media.

Synthetic Work

Three isostructural transition-metal arsenides and germanides, namely niobium nickel arsenide, Nb0.92(1)NiAs, niobium cobalt arsenide, NbCoAs, and niobium nickel germanide, NbNiGe, were obtained as inadvertent side products of high-temperature reactions in sealed niobium containers. In addition to reporting for the very first time the structures of the title compounds, refined from single-crystal X-ray diffraction data, this article also serves as a reminder that niobium containers may not be suitable for the synthesis of ternary arsenides and germanides by traditional high-temperature reactions. Synthetic work involving alkali or alkaline-earth metals, transition or early post-transition metals, and elements from groups 14 or 15 under such conditions may yield Nb-containing products, which at times could be the major products of such reactions.
