Structural insights into the usage of carboxylate ions as molecular pins

Structurally diverse coordination compounds of zinc as effective precursors of zinc oxide nanoparticles with various morphologies

“…The compounds containing outer coordination sphere species (1 and 5) decompose to ZnO particles larger than these created during decomposition of 2-4 (containing solely inner coordination sphere molecules) in E3. The largest particles are formed from compounds possessing the greatest number of outer coordination sphere ligands (5); however, such a general dependence cannot be postulated as only two of the studied compounds possess outer coordination sphere ligands. A fast conversion at increased temperature (800°C, E4) leads to melting of these precursors (due to the presence of water molecules in their structure) directly before their decomposition.…”

“…[1][2][3][4] The benefit of using coordination compounds results from the possibility to control both size and morphology of the nanoparticles by intentional modifications of a precursor structure. [5,6] This is extremely important, as achievement of unique properties of nanomaterials requires proper set-up of both the aforementioned features. Investigations into the antibacterial properties of three morphologically different zinc oxide particles (spherical, rod and flower-like) revealed that they exhibited different activities.…”

“…The scanning electron microscopy (SEM) micrographs of ZnO particles produced from coordination precursors(1)(2)(3)(4)(5) in four experiments (E1-E4) observed for precursors 3 and 4 in comparison with the mononuclear precursors 1 and 2. The larger heating rate leads to the smaller size of particles.…”

Structural Insights into Influence of Isomerism on Properties of Open Shell Cobalt Coordination System

“…Two variants of this method were applied. In the first one, samples of precursors (50 mg each) were heated with a heating rate of 5 °C∙min −1 , up to the temperature of CoO formation (370 °C, based on the thermal analyses of the coordination compounds), in air atmosphere [38]. In the second variant, precursors samples (50 mg each) were suspended in oleic acid (1.0 cm 3 ) and heated at 220 °C for 2 h. After this process, a small volume of toluene (0.5 cm 3 ) and a large excess of methanol (10 cm 3 ) were added to the suspensions, and black precipitates were separated by centrifugation.…”
