Acetylenedithiolate: alkyne complex formation renders it a dithiolate chelate ligand.
The isostructural complexes [{Tp'W(CO)(2)(eta(2)-C(2)S(2))}(2)M] (M = Ni, Pd, Pt) show that the eta(2)-C,C'-alkyne complexes of acetylenedithiolate at [Tp'W(CO)(2)](+) can generally act as dithiolate chelate ligands, leading to dithiolene type complexes.
متن کاملLight and dark adaptation of crayfish visual cells depending on extracellular calcium concentration.
Lowering of extracellular Ca2+-concentration from 14 X 10(-3) M to ca. 10(-6) M (using 1 mM ethyleneglycol bis (beta-aminoethylether)-N,N'-tetraacetic acid (EGTA)) results in weaker light adaptation by a 2 s light exposure and faster dark adaptation (half time 45 +/- 1%) of crayfish visual cells.
متن کاملThe Chromium-51 Complex of Ethylenediamine Tetraacetic Acid as a Soluble Rumen Marker.
In experiments on digestive function in ruminants, markers can be used to estimate the rate of movement of digesta, the volume of a viscus and the rates of absorption of solutes from the gut. The most widely used water-soluble marker is polyethylene glycol (PEG), which was introduced by Sperber, HydCn & Ekman (1953). They found that the polymer with mean molecular weight 4000 was not degraded i...
متن کاملDetachment and chemical characterization of the regularly arranged subunits from the surface of an Acinetobacter.
Acinetobacter sp. strain MJT/F5/199A carries an array of tetragonally arranged subunits on its outer surface. The subunits can be detached from isolated cell walls by incubation with 1 M urea or by washing with water after treatment with 10 mM ethylenediaminetetraacetic acid or ethyleneglycol-bis(beta-aminoethylether)N,N'-tetraacetic acid. After removal of the urea, they reaggregate into the sa...
متن کاملFunction of the classical and alternate pathways of human complement in serum treated with ethylene glycol tetraacetic acid and MgCl2-ethylene glycol tetraacetic acid.
An immunochemical and functional analysis of the classical and alternate complement pathways in human serum was performed in the presence of 10 mM ethylene glycol tetraacetic acid (EGTA) and MgCl(2)-EGTA (MgEGTA), chelating agents which have been recently utilized as a means of distinguishing between these two complement pathways. Total hemolytic activity, integrity of the C1 complex, hemolytic...
