Precisely controlled stoichiometric mixtures of Co(2+) and Fe(2+) metal ions were combined with the [W(V)(CN)8](3-) metalloligand in a methanolic solution to produce series trimetallic cyanido-bridged {Fe(9-x)Co(x)[W(CN)8]6(MeOH)24}·12MeOH (x = 0, 1, ..., 8, 9; compounds 9) clusters. All compounds, 0-9, are isostructural, consist pentadecanuclear clusters six-capped body-centered cube topology, capped by methanol molecules which coordinated 3d centers. Thus, they can be considered as unique...

The is linked presence of Cd, Cr, Cu, Ni, Pb, Zn street dust, which consists mineral organic particles originating from soil, industrial emitters, motor vehicles, fuel consumption. study objective was determine level dust contamination with trace Lublin indicate their potential sources origin. analyses were carried out an energy-dispersive X-ray fluorescence...
Abstract Bistable and stimuli‐responsive molecule‐based materials are promising candidates for the development of molecular switches sensors future technologies. The CN‐bridged {NH 4 [Ni(cyclam)][Fe(CN) 6 ]⋅5 H 2 O} n chain exists in two valence states: Ni II ‐Fe III ( 1 HT ) LT shows unique multiresponsivity under ambient conditions to various stimuli, including temperature, pressure, light, humidity, which generate measurable response form significant changes magnetic susceptibility color....
Novel bioactive organic–inorganic hybrid materials that can serve as injectable hydrogel systems for bone tissue regeneration were obtained. The silica nanoparticles (SiNP) prepared in situ by the Stöber method dispersed collagen, collagen-chitosan or chitosan sols, which then subsequently crosslinked. Laser scanning confocal microscopy studies, fluorescent SiNP applied, and SEM images indicated nanosilica particles distributed whole volume of matrix. In vitro studies on fibroblast cell...
A bimetallic pentadecanuclear cyanido-bridged {Fe9[W(CN)8]6 (MeOH)24}·xMeOH cluster of an FeII/III–WIV/V mixed valence nature, reveals a reversible single-crystal-to-single-crystal transformation, concomitant with metal-to-metal charge transfer between Fe and W ions. The dominance HSFeII–NC–WV units at high temperature, HSFeIII–NC–WIV low leads to unprecedented reversed thermal hysteresis loop in magnetic measurements.
Two new hexanuclear octahedral cyanido-bridged clusters, {[CdII(bpy)2]4[WIV(CN)8]2}·10H2O (Cd4W2) and {[CdII(bpy)2]4[MoIV(CN)8]2}·10H2O (Cd4Mo2), have been obtained characterized structurally photomagnetically. Both compounds show a very rare reversible single-crystal-to-single-crystal transformation upon dehydration accompanied by marked color changes in the case of Cd4W2. Moreover, irradiation Cd4Mo2 using 436 nm light induces photomagnetic effect due to LIESST-like singlet-triplet...

In the natural, high-pressure environments of sediments and sedimentary rocks, clay minerals, along with organic matter, contribute to a large portion available surface area microporosity in which methane (CH4) can be adsorbed. However, most questions concerning location adsorption sites, e.g. interlayer accessibility for CH4, remain unknown. Here, we have separately investigated textural structural control on CH4 pure minerals by combining high- low-pressure gas techniques, transmission...
Reaction between [Ni(cyclam)](2+) and [W(CN)(8)](4-) leads to the formation of a 3D diamond-like network [Ni(cyclam)](2)[W(CN)(8)]·3.5H(2)O (1). The structure is characterised by intersecting channels 3-4 Å in diameter, filled with crystallisation water, most which released upon drying air, causing crystals collapse. Analogous compound [Ni(cyclam)](2)[Nb(CN)(8)]·3.5H(2)O (2), based on paramagnetic Nb(IV), could only be obtained as powder, due decomposition [Nb(CN)(8)](4-) complex under slow...
