Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis configuration, the two chloride ligands are adjacent to each other. The other isomer...
Nitrite reduction by cytochrome cd(1) nitrite reductase (cd(1)NIR) is currently accepted to involve coordination of the nitrite nitrogen atom to the ferrou... R Silaghidumitrescu - 《Inorganic Chemistry》 被引量: 72发表: 2004年 Isomerism of the Metal Complexes containing Multidentate Ligands. I...
optical stereoisomerismSome peculiarities of the effect of enantiomers of the monodentate ligand on the stereoisomerism of the mixed octahedral tetrafluoride complexes of d(0)-transition metals are established by the F-19{H-1} and (31)?{H-1} NMR methods for the complex formation of TiF4 ...
Unsymmetrical bidentate ligands of alpha-aminoaldimines leading to sterically controlled selectivity of geometrical isomerism in square planar coordination. Newα-aminoaldimines with the formula of Et2NCMe2CHNR (R =iPr,tBu, Ph) and their dichloro or diacetato complexes of Ni, Pd, Pt are prepar...
Structural study of semi-coordination in a seven-coordinate copper(II) complex: distortion isomerism of [Cu(CH3COO)2(4-aminopyridine)2(H2O)] [Di(acetato)bis(4-aminopyridine)aquacopper(II)] exists in two different monoclinic forms. The crystal structure of Form 1, which crystallizes in space...
. Only motif B has been previously found in Ag cluster42and the two binding modes have been also reported in other transition metals (e.g., Cr, Mo)43,44. Interestingly, the amido N of dpa could also ligate two metal atoms (motif C and motif D), so that the maximum coordination ...
As past experience has shown in the case of drug thalidomide [145], sometimes not controlling the stereoisomerism of drugs can have serious consequences. The racemic drug thalidomide was widely used in the 1960s to treat nausea during pregnancy in many countries. While the d-form of ...
Optical isomerism due to asymmetric coordination of some olefins such as propylene and trans-2-butene was first studied by Paiaro and Panunzi.lWe have synthesized diastereomers of the type...doi:10.1007/978-1-4684-2142-2_29Kazuo Saito
Evidences for influence of both wingtip substituents and optical isomerism on the biological activities of the complexes have been found. Bidentate palladium complexes bearing N﹉eterocyclic carbene and pyridine ligands were optically resolved. Biomedical application studies revealed that they exhibited ...
1. Introduction For the development of new interesting materials based on coordination compounds, polytopic or polyfunctional ligands are interesting candidates [1–10]. Both types can help to selectively assemble discrete mononuclear or polynuclear complexes [1–4,7–9], clusters [6,7], or ...
