چکیده
Isomeric complexes of platinum, which contain two non-innocent ligands are reported. The built-in coordination asymmetry in the ligands makes it possible to separate two different positional isomers. Results from X-ray crystallography is used to invoke the popular structure oxidation state correlation in these complexes. The redox processes are discussed and interpreted with the help of UV-vis-NIR and EPR spectroelectrochemistry.

Isomeric separation in donor-acceptor systems of Pd(II) and Pt(II) and a combined structural, electrochemical and spectroelectrochemical study.
Compounds of the form [(pap)M(Q(2-))] (pap = phenylazopyridine; Q = 3,5-di-tert-butyl-benzoquinone, M = Pd, 1a and 1b, M = Pt, 2a and 2b; Q = 4-tert-butyl-benzoquinone, M = Pd, 3a and 3b; M = Pt, 4a and 4b) were synthesized in a one-pot reaction. The geometrical isomers, which are possible because of the built in asymmetry of these ligands, have been separated by using different temperatures an...

The reactivity of metal olefin complexes with non-innocent ligands (NILs) was examined. Treatment of PtCl(2)(diene) with the deprotonated catechol or aminophenol ligands afforded the corresponding Pt(NIL)(diene) complexes. The Pt((t)BA(F)Ph)(COD), Pt((t)BA(F)Ph)(nbd), and Pt(O(2)C(6)H(2)(t)Bu(2))(COD) (H(2)(t)BA(F)Ph = 2-(2-trifluoromethyl)anilino-4,6-di-tert-butylphenol, H(2)O(2)C(6)H(2)(t)Bu(...

In the title mononuclear complex, [Ru(C14H20O2)2(C10H8N2)], the RuII ion has a distorted octa-hedral coordination environment defined by two N atoms of the chelating 2,2'-bi-pyridine ligand and four O atoms from two 3,5-di-tert-butyl-o-benzo-quinone ligands. In the crystal, the complex mol-ecules are linked by inter-molecular C-H⋯O hydrogen bonds and π-π stacking inter-actions between the 2,2'-...
