چکیده
The title compound, C(7)H(4)BrNO, crystallizes with two mol-ecules in the asymmetric unit. The two molecules exhibit nearly linear C-C N nitrile bond angles of 179.1 (4) and 177.1 (4)°. In the crystal, the mol-ecules are linked into a one-dimensional hydrogen-bonded chain by inter-actions between the phenol H atom and the nitrile N atom [N⋯O = 2.805 (4) and 2.810 (4) Å].

In the title centrosymmetric dinuclear complex, [Nd(2)(C(27)H(24)Br(3)N(4)O(3))(2)]·6C(3)H(7)NO, the Nd(III) ion is coordinated in a slightly distorted square-anti-prismatic geometry by four N atoms and four O atoms from two centrosymmetrically-related 1,3-bis-[2-(5-bromo-2-oxidobenzyl-amino)eth-yl]-2-(5-bromo-2-oxidophen-yl)-1,3-imidazolidine ligands. The Nd⋯Nd separation is 4.5012 (12) Å.

The title compound, C18H13Br3N2S2, was obtained via the reaction of N-bromo-succinamide with 5,6-dimethyl-2-(thio-phen-2-yl)-1-[(thio-phen-2-yl)meth-yl]-1H-benzimidazole. The compound exhibits rotational disorder of the 5-bromo-thio-phen-2-yl substituent with a refined major:minor occupancy ratio of 0.876 (7):0.124 (7). The 5-bromo-thio-phen-2-yl mean plane is canted to the benzimidazole plane ...
متن کاملEffect of 5-bromo-2-deoxyuridine on transport of deoxyglucose and cycloleucine in 3T6 fibroblasts.
When 3T6 mouse fibroblasts in culture are grown in the presence of 5-bromo-2-deoxyuridine (50 /ig/ml), they reach a saturation density which is only 50% of the satura tion density reached by untreated control 3T6 cells. The up take of deoxyglucose-3H and of cycloleucine-14C is de creased in cells grown in the presence of 5-bromo-2-deoxyuridine. The uptake of deoxyglucose-3H is also decreased in...
متن کامل5-bromo-2'-deoxyuridine-stimulated calcium ion- or magnesium ion-dependent ecto-(adenosine triphosphatase) activity of cultured hamster cardiac cells.
1. Treatment of hamster heart cells in primary culture with 5-bromo-2'-deoxyuridine resulted in the greatly increased activity of a particulate Ca2+- or Mg2+-dependent ATPase (adenosine triphosphatase). 2. 5-Bromo-2'-deoxyuridine exerted these effects only when it was incorporated into cellular DNA, and then in a concentration-dependent manner. 3. Serially replated cells contained less of the ...
متن کاملA Sandmeyer type reaction for bromination of 2-mercapto-1-methyl-imidazoline (N2C4H6S) into 2-bromo-1-methyl-imidazole (N2C4H5Br) in presence of copper(I) bromide.
2-Mercapto-1-methyl-imidazoline (N(2)C(4)H(6)S) is converted at room temperature into 2-bromo-1-methyl-imidazole (N(2)C(4)H(5)Br) in presence of copper(I) bromide in acetonitrile-chloroform mixture via extrusion of sulfur as sulfate and oxidation of Cu(I) into Cu(II). 2-Bromo-1-methyl-imidazole was isolated as its self assembled tetranuclear Cu(II) cluster, [Cu(4)(η(1)-N-(N(2)C(4)H(5)Br)(4)(μ(4...
