چکیده انگلیسی
Tantalum(V) form bis(amidopyridine) complexes with pentagonal bipyramidal coordination spheres. The polyhedra were evaluated by calculating least-square mean planes through M–N4–Cl equatorial-atoms. Distortion of the pentagonal plane can be seen as small tilting of the chelate rings. Isomerism can be affected by substituents in the amidopyridine ligands.
The structures of tantalum amidopyridine complexes were studied by X-ray diffraction. The seven-coordinated mononuclear bis(amidopyridine) complexes displayed configurational isomerism in the crystalline state. Distortions in the coordination polyhedra around the Ta center were evaluated.Figure optionsDownload as PowerPoint slide
