Compared to the large number of main group Zintl compounds there are only a few that contain transition metals.[1] This is not surprising since the traditional definition of Zintl phases automatically excludes transition metals. However, many such compounds with transition metals can qualify for Zintl phases when a broader definition is used. The latter includes compounds of transition metals w...

Bis(diphenylthiophosphoryl)amine, a weak protic acid, can be readily deprotonated. The alkali salts [Ph2P(S)]2NM have been used to prepare S-bonded complexes with transition metals containing a NP2S2M six membered ring [1]. Although the struc­ tures of the neutral ligand [Ph2P(S)]2NH [2] and of several transition metal complexes [1] have been de­ termined by X-ray diffraction techniques, struct...

The protein family of anion channel (ClC) constitute a family of transmembrane trnsporters that either function as anion channel or as H+/anion exchanger. The expression of three genes of AtClCa, AtClCb and AtClCd in the model plant Arabidopsis thaliana were silenced by a T-DNA insertion . When the pH of the medium was slightly acidic the length of the primary root of plants with a disrupted At...

Anionic, electron-releasing phosphines that incorporate a borate counteranion within the ligand framework are promising reagents for organometallic catalysis. This report describes the synthesis of a new class of monodentate tertiary phosphines built upon the commonly employed tetraphenylborate anion. These new phosphines are highly stable and strongly electron-releasing and readily coordinate ...

The syntheses of the first carboranyl N-heterocyclic carbene complexes with transition metals are reported. Both unsymmetrical mono-anionic and symmetrical dianionic NHCs readily react with ClAuSMe2 to afford unusual zwitterionic and anionic Au(i) dimethyl sulfide adducts. The compounds are characterized by NMR, mass spectrometry, and single crystal X-ray diffraction studies. Percent buried vol...

In this article, based on electronic structure calculations, the conditions are discussed under which a genuine half-metallic interface between a heusler C1b half-metal and a semiconductor can exist. An explanation is given why for the III–V semiconductors the double anion terminated (111) interface is the only possible interface. For semiconductors, based on transition metals, a much wider var...

Using vibrationally resolved ultraviolet photoelectron spectroscopy, we studied oxygen adsorption on W monomer anions. Three oxygen atoms are atomically bound in a WO3- compound, whereas in WO4- the fourth oxygen atom is attached to the oxygen, forming a di-oxygen species, implying that atom to molecule transition of O2 takes place when the number of oxygen atoms attached to a W monomer anion e...

tio2 nanoparticles, as a photocatalyst for oxidation of dimethyl methylphosphonate (dmmp) as an organophosphorus simulant of chemical warfare agent, were prepared by using sol-gel method. the prepared nanoparticles were then modified with transition metals in order to decrease the electron-hole recombination and increase the photocatalytic activity. transition metal ions including pt, pd and ni...
