Quality Control of cis-Dichlorobis(pyridine)platinum(II). The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: cis-Dichlorobis(pyridine)platinum(II), is researched, Molecular C10H10Cl2N2Pt, CAS is 15227-42-6, about Preparation and spectroscopic investigations of platinum complexes. I. Interpretation of the spectra of inverse electron transfer and ligand field transitions of platinum(II) complexes with halide and nitrogen ligands. Author is Textor, M.; Ludwig, W..
Inverse electron-transfer transitions of the type, 5d(Pt) → π(L), were detected in the electronic absorption spectra of cis- and trans-PtL2X2 complexes in which N-containing ligands have an internal π-electron system (L = pyridine, 3- or 4-chloropyridine, 3,5-dichloropyridine, 4-pentyl- or 4-cyanopyridine, or piperidine; X = Cl, Br, or I). In addition to ligand-field (d-d) and ligand π-π* transitions, 3 charge-transfer transitions were distinguished in the spectra of these complexes in CH2Cl2 or cyclohexane solutions Quant. correlation was established between energy of the ligand field transitions and energy of the inverse charge-transfer transitions.
