The title compound, {[Cu(2)(C(8)H(5)Cl(2)O(3))(C(10)H(8)N(2))(2)]NO(3)}(n) was prepared by reacting copper(II) nitrate with 4,4'-bipyridine (4,4'-bipy) and (2,4-dichloro-phen-oxy)acetic acid under solvothermal conditions. Each of two copper(I) atoms in the asymmetric unit is three-coordinated by two N atoms from two 4,4'-bipy ligands and one O atom from the (2,4-dichloro-phen-oxy)acetate ligand...

a potent antagonist of riboflavin in the rat, has been found to be nonspecific in the inhibition of the growth of Walker rat Carci noma 256. 7-Ethyl-8-methyl-10-(r-D-ribityl)isoalloxazine (7ethyl-8-methyIflavin) and 7-methyl-8-ethy 1-10-(1' -D-ribityl) isoalloxazine (7-methyl-8-ethylflavin) have been found to replace riboflavin for the growth of and the efficiency of utilization of food by the ...

A strain of streptomycete was found to produce a new antibiotic pyrroxamycin. This compound was isolated from the culture broth of Streptomyces sp. S46506. The chemical structure was determined to be 4,5-dichloro-2-(6',8'-dichloro-4'H-1',3'-benzodioxin-4'-yl)-3-nitr opyrrole by its chemical character and 1H and 13C NMR spectral analysis. Pyrroxamycin was active against Gram-positive bacteria an...

The reaction of alkaline 2,4-dihydroxyquinoline 1 and 1-tetralone 2 in 2% sodium hydrox­ ide solution with vinyl acetate afforded a brown solid 3, which on treatment with phospho­ rous oxychloride yielded 2,4-dichloro-3-[l’-(l-chloro-naphth-2-yl)ethyl]quinoline (4). The same reaction of 1 and chromanone 7 with vinyl acetate afforded 2,4-dichloro-3-[l’-(4-chloro2-methyl-chromen-3-yl)ethyl]quinol...

The occurence of “exotic” shapes in light N=Z α-like nuclei is investigated for 24Mg+12C and 32S+24Mg. Various approaches of superdeformed and hyperdeformed bands associated with quasimolecular resonant structures with low spin are presented. For both reactions, exclusive data were collected with the Binary Reaction Spectrometer in coincidence with EUROBALL IV installed at the VIVITRON Tandem f...
