“…Some of them are capable of reductive N 2 splitting to nitrido complexes and subsequent formation of ammonia. 4 Among the ligands used for such applications, aromatic organochalcogenolates (ArE − with E=O, S, Se or Te) represent an interesting and versatile class [6–9] . The coordination chemistry of rhenium complexes containing organothiolato ligands is well known with thoroughly performed structural studies and well explored synthetic pathways [10–16] .…”

In situ prepared lithium arylselenolates {LiSePh, LiSe(2,6-Me 2 Ph), LiSe(2,4,6-Me 3 Ph)} or -tellurolates {LiTePh, LiTe(2,6-Me 2 Ph), LiTe(2,4,6-Me 3 Ph)} react with [ReOCl 3 (PPh 3 ) 2 ] and (NBu 4 )Br in good yields under formation of rhenium(V) complexes of the composition (NBu 4 )[ReO(L) 4 )]. The first oxidorhenium(V) complex with four monodentate phenolato ligands, [ReO(2,6-Me 2 Ph) 4 ] À , was prepared and isolated in crystalline form. This allows a comparison of experimental and computational data of a full series of such compounds with basal O, S, Se and Te donor atoms. Similar reactions with [ReCl 3 (PPh 3 ) 2 (CH 3 CN)] or [ReCl 3 (PMe 2 Ph) 3 ] give trigonal bipyramidal rhenium(III) complexes of the compositions [Re(PPh 3 )(L) 3 (CH 3 CN)] or [Re-(PPh 3 ) 2 (L) 3 ] depending on the chalcogenolate applied. The reported oxidorhenium(V) and rhenium(III) complexes were fully characterized by spectroscopic methods and X-ray diffraction. The bonding situation in the rhenium(V) and rhenium(III) chalcogenolates was assessed through density functional theory calculations based on the quantum theory of atoms in molecules (QTAIM), natural bonding orbital (NBO) analysis, charge analysis, the electron localization function (ELF) maps and topological descriptors at the {3,À 1} critical points such as metallicities. Expectedly, the ionicity of the rhenium-chalcogen bonds decreases according to all three applied charge models from O to Te. Generally, the ReÀ Se and ReÀ Te bonds are more directional in the Re(III) complexes than in the oxidorhenium(V) compounds.

“…Nevertheless, most of the methods for the synthesis of HgSe nanostructures deal with either toxic chemicals or air-sensitive chemicals which need to be handled in glove boxes. Although quite a few mercury chalcogenolate precursors with crystal structures have been reported in the literature recently, , there is no precursor which has been transformed into HgSe ordered structures. Therefore, there is a critical need for a straightforward strategy that utilizes air-stable precursors, making the synthesis of HgSe-ordered structures more accessible and manageable.…”

Achieving a one-pot synthesis of porous HgSeordered structures endures a challenging and unexplored goal, necessitating a straightforward protocol. Contextually, the present study describes a single-source molecular precursor approach for the synthesis of self-assembled porous HgSe rod superstructures (SSs) built by HgSe nanorods via hot injection of [HgCl(SeC 4 H 3 N 2 )tmeda] in oleylamine (OAm). Both the molecular precursor and the pristine HgSe rod SSs were characterized by multiple experimental tools. Furthermore, the mechanism for superstructure formation has been elucidated through crystal packing analysis using single crystal X-ray diffraction, supported by small-angle X-ray scattering (SAXS) measurements. The photoresponsive application of superstructures was assessed by using a liquid junction photoelectrochemical cell.
