Ca 2 1 -activated Cl channels (Cl Ca Cs) are an important class of anion channels that are opened by increases in cytosolic [Ca 2 1 ]. Here, we examine the mechanisms of anion permeation through Cl Ca Cs from Xenopus oocytes in excised inside-out and outside-out patches. Cl Ca Cs exhibited moderate selectivity for Cl over Na: P Na / P Cl 5 0.1. The apparent affinity of Cl Ca Cs for Cl was low: ...

In this contribution, the synthesis and properties of nine novel 3d metal complexes are reported. As supporting ligand scaffold, bulky 1,8-bis(3,5-ditertbutylphenyl)-3,6-ditertbutylcarbazole (R) was employed. After deprotonation salt metathesis reactions, a series four complexes, dimeric [RMn(THF)(μ-Cl)]2 (1 a), [RFe(THF)(μ-Cl)]2 (2 [RCo(THF)(μ-Cl)]2 (3 a) as well monomeric [RCr(THF)2(Cl)] (4 w...

The electron capture dynamics of halocarbon and its water complex have been investigated by means of the full dimensional direct density functional theory molecular dynamics method in order to shed light on the mechanism of electron capture of a halocarbon adsorbed on the ice surface. The CF(2)Cl(2) molecule and a cyclic water trimer (H(2)O)(3) were used as halocarbon and water cluster, respect...

Herein we report the synthesis and structural characterization of four novel polychloride compounds. The compounds [CCl(NMe2)2][Cl(Cl2)3] [NPr4][Cl(Cl2)4] have been obtained from reaction corresponding chloride salts with elemental chlorine at low temperature. They are missing links in series monoanions [Cl(Cl)n]? (n=1–6). Additionally, decamethylferrocene was studied yielding [Cp*2Fe]2[Cl20], ...
