The present article deals with a newer class of ligand bridged asymmetric complexes incorporating ancillary ligands (AL) with varying electronic characteristics: [(bpy)2Ru(II)(μ-HL(2-)) Ru(II)(bpy)2](ClO4)2·([1](ClO4)2); [(pap)2Ru(II)(μ-HL(2-))Ru(II)(pap)2](ClO4)2 ([2](ClO4)2); [(bpy)2Ru(II)(μ-HL(2-))Ru(II)(pap)2](ClO4)2 ([3](ClO4)2); [(acac)2Ru(III)(μ-HL(2-))Ru(III)(acac)2] (4) and [(bpy)2Ru(I...

The synthesis and characterization of multinuclear complexes [Pd(acac)(fcdpm)] (1), [Pd(fcdpm)(2)] (2), [Co(acac)(fcdpm)(2)] (3), [Co(fcdpm)(3)] (4) and α-alkoxy derivatives [α-OMe-fcdpm] (5), [α-OEt-fcdpm] (6), [α-OPr(n)-fcdpm] (7) and [α-OBu(n)-fcdpm] (8) (fcdpm = 5-ferrocenyldipyrromethene; acac = acetylacetone) have been described. Formation of alkoxy derivatives 5-8 takes place from highly...

Casiopeínas® is a family of copper complexes with the general formulae [Cu(N-N)(N-O)]NO3 and [Cu(N-N)(O-O)]NO3; where N-N = substituted aromatic diimine (2,2’-bipyridine (bipy) or 1,10-phenanthroline (phen)); N-O = α-aminoacidate or a peptide; and O-O = acetylacetonate (acac) or salicylaldehydate. These compounds have shown antiproliferative activity in vitro and antitumor activity in several m...

The reaction of Dy(NO(3))(3)·6H(2)O with the ligand 2-((1-hydroxybutan-2-ylimino)methyl)phenol (H(2)L, ) generates the nonanuclear compound [Dy(9)L(8)(μ(3)-OH)(8)(μ(4)-OH)(2)(CH(3)OH)(8)](OH)(CH(3)OH)(3) (Dy(9)), whose single-crystal X-ray structure reveals the presence of two square pyramidal pentanuclear units assembled via the apical metal center. The square pyramidal core of a previously re...

LITTLE, JOHN R., MASAI-URO GOTO, AND JOHN J. SPITZER. E$ect of ketones on metabolism of FFA by dog myocurdium and skeletal muscle in Go. Am. J. Physiol. 219(5): 1458-1463. 1970.-The uptake of P-hydroxybutyrate (p-OHB), acetoacetate (AcAc), and free fatty acids (FFA) by the myocardium and the thigh skeIeta1 muscle of mongrel dogs was measured under control conditions and during the infusion of N...

Reaction of a tetraphenyl-1,2-diphosphinyl dianion with [FeCl2(THF)1.5] or [Ru(COD)(acac)2] yields dianionic complexes which further react with Ph3SnCl to afford the corresponding bis(1,4-diphosphabutadiene) complexes.

A general method for synthesis of supported metal complexes having a high degree of uniformity is presented, whereby organometallic precursors incorporating acetylacetonate (C(5)H(7)O(2)(-), acac) ligands react with zeolites incorporating OH groups near Al sites. The method is illustrated by the reactions of Rh(acac)(CO)(2) and of cis-Ru(acac)(2)(eta(2)-C(2)H(4))(2) with zeolites slurried in n-...

Highly sensitive semiconductor gas sensors hold great potential for applications in trace detection. Reliable detection of ppb-level NO2 is crucial environmental monitoring, which however still remains a challenge. In this work, we adopted one-pot encapsulation strategy synthesizing indium-doped ZnO porous hollow cages. In(acac)3 was selected as the indium source due to its molecular diameter b...

Three dinuclear [Ln2H2OL(1)2(acac)2]·solvent (1, Ln = Gd, solvent = 2CH2Cl2; 2, Ln = Tb, no solvent; 3, Ln = Er, solvent = (C2H5)2O), and two tetranuclear lanthanide clusters [Ln4(μ3-OH)2L(2)2(acac)6]·2(solvent) (4, Ln = Tb, solvent = CH3OH; 5, Ln = Dy, solvent = CH3CN) were characterized in terms of structure, fluorescence and magnetism. The dinuclear lanthanide complexes were constructed by a...
