SummaryComplexes of the type M(4-ADI)nX2 " ml-120 (where 4-ADI = 4~amino-3,5-dimethylisoxazole; n = 1-4; X = CI, Br, 1, SCN, CIO4; m = 1-4) have been studied by i.r. and electronic spectroscopy, magnetic and conductivity measurements. The ligand behaves as a monodentate -NH2 bondcd species in monomeric complexes, but as a bridging ligand -NH2 and -N(ring) bonded species in polymeric complexes. All the compounds have an octahedral stereochemistry, except Co(4-ADI)2X2 (X = CI, Br, 1) complexes, which are tetrahedral.
405methylpropylcetone a aussi ete observk vis-a-vis de l'ion borohydrure, et serait diie une conformation pseudocyclique de la molecule stabilisant I'etat initialz2. Pour la diethylcetone (23) on constate qu'il y a additivite des effets observes sur la methylethylcetone (18) par rapport ii l'acetone (17). (Received June 28th. 1978) Abstract. A number of compounds of general formula M(PPO),X, are described, the metal ion being Zn(ll), Cd(I1) and Hg(I1) and the anions C1-, Br-, I -, NO,-, C10,-and NCS-; PPO stands for 2,5-diphenyloxazole and n = 1, 2, 4. The complexes are prepared by reaction of the corresponding metal salts with the molten ligand in the required stoicheiometrical ratio and are characterized by chemical analyses and physical measurements. Their stereochemistry has been assigned on the basis of IR, far IR spectroscopy and molar conductivity values. The ligand PPO is shown to co-ordinate with metal ions via the lone-pair electrons of the nitrogen atom. All the complexes have generally a distorted tetrahedral stereochemistry.
MkthylWe previously investigated the properties of Cu( II), Ni( I I) and Co(l I) complexes with 2,s-diphenyloxa~ole~. This ligand acts both as a monodentate N-bonded and as a bridging Nand O-bonded ligand.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
