Direct approaches to zinc polychalcogenide chemistry: ZnS6(N-MeIm)2 and ZnSe4(N-MeIm)2

Abstract

N‐Methylimidazole suspensions of zinc exhibit particularly well behaved reactivity toward sulfur yielding the hexasulfide (III) (space group P1, Z=2).

Vertically aligned and hexagonal crystal ZnSe nanoribbon arrays on Zn substrates

“…In our case, we think that en has played a similar role as SCMT. However, the nanoribbons synthesized in our process are almost vertically aligned arrays on the Zn foil rather than the randomly orientated as synthesized by others [20,22]. This leads us to propose that the growth procedure ZnSe precursor nanoribbon array in our case is related to both electrochemical reaction and SCMT mechanism.…”

Organic Cation and Complex Cation‐Stabilized (Poly‐)Selenides, [Cation]x(Sey)z: Diversity in Structures and Properties

“…[3] In contrast, organic cation-stabilized selenides -that is, salts of well separated (poly-)selenide anions (Se x ) 2-besides purely organic cations or solvated / coordinated metal ions, respectively -have been lesser focused on, although their solubility in both aqueous and organic solvents makes them ideal for processing [4] or further reactions towards new materials. As an alternative to the usage of in situ-generated polyselenides, where the corresponding reagents serve as both precursor and reducing agent at the same time [5] [see, for example, Equation (1) and Equation (2); N-MeIm = N-methylimidazole], or preformed polyselenides with varying and undetermined chain lengths, [6] the application of crystalline polyselenides as well defined starting materials can additionally help understanding basic reaction mechanisms, for instance towards complicated metalates with different chain lengths of polyselenide ligands. known from literature are reviewed, along with the crystal structures of new compounds and some spectroscopic data, and an experimental and theoretical approach towards dichroism observed in some of the triselenides.…”

Preparation and Characterization of Metal Sulfides in Ethylenediamine under Ambient Conditions through a γ-Irradiation Route

“…So we attributed the diffraction peaks to the stable coordination phase which consisted of zinc, sulfur, and ethylenediamine. In analogy, zinc reacts with sulfur in a strongly coordinating solvent (N -methylimidazole) and forms complexes of ZnS 6 (N -MeIm) 2 as has been reported elsewhere (20). Infrared spectrum studies also suggest an interaction between the amino group and zinc atoms (21).…”
