چکیده

The reaction of Rb4Sn4 with ZnPh2 in liquid ammonia in the presence of [2.2.2]-cryptand yielded crystals of Rb6[(η(2)-Sn4)Zn(η(3)-Sn4)]·5NH3, which could be characterized by single crystal X-ray diffraction. This is the first example of a successful solution reaction of the highly charged tetrahedral Sn4(4-) anions. The homoleptic [E4ZnE4](6-) complex (E = tetrel element) was previously known only for E=Ge and Si/Ge.

A Step in Between : [ Sn 3 Bi 3 ] 5 and Its Structural

Extraction of “RbSnBi” in liquid ammonia yielded the cluster anion [Sn3Bi5] 3 , which could be crystallized in the compound [Rb@[2.2.2]crypt]3[Sn3Bi5]·8.87NH3. This anion is found to be derived from the formerly reported [Sn4Bi4] 4 by the formal substitution of one tin atom by bismuth. In contrast, the extraction of “RbSn2/Rb3Bi2” in liquid ammonia yielded the anion [Sn3Bi3] 5 in the compound R...

How does cyanide inhibit superoxide reductase? Insight from synthetic FeN4S model complexes

and CN2 have been shown to bind to the catalytic iron site of SOR, and cyanide acts as an inhibitor. To understand how these exogenous ligands alter the physical and reactivity properties of the SOR iron site, acetate-, azide-, and cyanide-ligated synthetic models of SOR have been prepared. The x-ray crystal structures of azideligated [Fe(SN4(tren))(N3)] (3), dimeric cyanide-bridged ([Fe(SN4(tr...

First Incorporation of the Tetrahedral [Sn4]4- Cluster into aDiscrete Solvate Na4[Sn4](NH3)13 from Solutions of Na4Sn4 in Liquid Ammonia

The solution chemistry of nine-atomic group 14 Zintl clusters [E9] (E = Si–Pb) shows a fascinating diversity. Mild oxidation or oxidative coupling of these clusters lead to free radicals or dimeric, oligomeric and polymeric structures of the elements [1 – 5]. Further oxidation even results in new element allotropes with tetrahedrally connected tetrel atoms [6], and structures that are exclusive...

Insights into the enhanced photoelectrochemical performance of hydrothermally controlled hematite nanostructures for proficient solar water oxidation.

In this paper, we focus on the controlled growth mechanism of α-Fe2O3 nanostructures via the hydrothermal method. The field emission scanning electron microscopy (FESEM) results reveal that at a lower hydrothermal time, the initial nucleation involves the formation of short and thin β-FeOOH nanorods. The subsequent increase in the hydrothermal time leads β-FeOOH to form thicker and longer nanor...
