The following salts have been synthesized and structurally characterized: Na[IrF]·2HO (2/, = 6.6327(4), = 10.0740(6), = 5.9283(5) Å, β = 122.3880(10)°) and Na[IrF]·2HO (-3, = 7.5963(3), = 7.5963(3), = 9.8056(4) Å) (for the first time) by single-crystal X-ray diffraction; the unit cell parameters of a tetragonal phase ( /, = 5.005(2), = 10.074(4) Å) of the stable α-Na[IrF] were determined for the first time; and the unit cell parameters of β-Na[IrF] (321, = 9.332(4), = 5.136(2) Å) and Na[IrF] (2/, = 5.567(4), = 5.778(4), = 8.017(2) Å, β = 90.41(2)°) were determined using powder X-ray diffraction (PXRD). The data of the thermal stability was obtained by differential thermal analysis (DTA) for all substances. The presence of Na[IrF]·HO monohydrate is predicted. H[IrF] was prepared in a solution and was demonstrated to behave as a strong dibasic acid.

Water pollution, oxidative stress and the emergence of multidrug-resistant bacterial strains are significant global threats that require urgent attention to protect human health. Nanocomposites that combine multiple metal oxides with carbon-based materials have garnered significant attention due to their synergistic physicochemical properties and versatile applications in both environmental and biomedical fields. In this context, the present study was aimed at synthesizing a ternary metal-oxide nanocomposite consisting of silver oxide, copper oxide, and zinc oxide (ACZ-NC), along with a multi-walled carbon nanotubes modified ternary metal-oxide nanocomposite (MWCNTs@ACZ-NC).

On a silicon substrate, a titanium film served as the electrode layer, and an aluminium film served as the base layer in the initial film structure. A PAA template was formed from the Al film using two-step electrochemical anodizing.

Cyclopentadienyl anions ([Cp]) are pervasive ligands in coordination chemistry. In contrast, heavy-element derivatives of these ligands, particularly those that feature arsenic, are not as well developed. In this work, a new arsenic-based heterocycle with a structure analogous to [Cp] is presented.
