The synthesis, spectroscopic and magnetic characterization of a series of new alkoxo-bridged binuclear copper (II) compounds are described. All complexes have the general formula [Cu (m-OR)(L)2]2(ClO4)2 · x H2O, in which m-OR = CH3O-, C2H5O- or C3H7O-<e...
Coordination complexes (1–4) of 2-amino-4-methylbenzothiazole and 2-amino-3-methylpyridine with Cu(CH3COO)2 AgNO3 were prepared characterized by UV/Vis FT-IR spectroscopy. The molecular structure for single crystals silver (2 4) determined X-ray diffraction. coordination complex (2) is monoclinic space group P21/c, wherein two ligands are coordinated to a metal ion, affording distorted trigonal...
Reaction of isopropyl[(2-pyridyl)alkyl]amines such as N-isopropyl-N-2-methylpyridine or N-isopropyl-N-2-ethylpyridine with aqueous solutions of NaAuCl(4) led to the formation of [LAuCl(2)][AuCl(4)] in low yields, where L = pyridyl amine bound to gold in a bidentate fashion. Reaction of 2-(3,5-diphenyl-1H-pyrrol-2-yl)pyridine with aqueous NaAuCl(4), however, proceeded with formal loss of HCl and...
SM-1652 (sodium 7-[D(-)-alpha-(4-hydroxy-6-methylpyridine-3-carboxamido)-alpha-(4-hydroxyphenyl)acetamido]-3-[(1-methyl-1H-tetrazol-5-yl) thiomethyl]-3-cephem-4-carboxylate) is a new semisynthetic cephalosporin derivative with a broad spectrum of antibacterial activity. Its in vitro activity against gram-positive bacteria was comparable to that of cefazolin. SM-1652 exceeded cefazolin in potenc...
