Author is Agarwala, Badri Vishal.

Electronic absorption spectra and magnetic CD (MCD) spectra were studied for the square planar complexes cis- and trans-Pt(py)2Cl2 and Pt(2,2′-bipyridine)Cl2(I). Detailed studies were carried out for I due to its fair solubility in many solvents and the solvent effect on its electronic spectra was investigated. The band assignments of the electronic spectra are discussed and are supported by the MCD spectra. NMR and magnetic studies were also carried out on the complexes to further elucidate their configuration. All the complexes studied are diamagnetic in conformity with their square planar arrangement.

Compound: cis-Dichlorobis(pyridine)platinum(II), is researched, Molecular C10H10Cl2N2Pt, CAS is 15227-42-6, about The infrared spectra (500-150 CM-1) of the platinum complexes cis- and trans-[Pt(pyridine)2X2] (X = Cl, Br, I, SCN).

The IR spectra of cis and trans-[Pt(pyridine)2X2](X = Cl, Br, I, SCN) are discussed. The distinction between the νPt-X bands is based on their relative sensitivities to 15N-labeling and deuteration of the pyridine ring, to halogen substitution and to 15NCS-labeling. Two νPt-N and 2 νPt-X bands are observed in the cis-complexes as required for C2v symmetry. The D2h symmetry of the trans complexes requires 1 νPt-N and 1 νPt-X band but addnl. bands are observed and are ascribed to coupling between νPt-N and νPt-X.

An IR and Raman spectroscopic investigation of crystalline PdPy2Cl2 was made. The vibrational frequencies were measured in the region from 3500 to 30 cm-1. The assignments of the observed bands were made on the basis of the frequency calculation for trans- and cis-PdPy2Cl2 plane and nonplanar configurations, using force constants, modelled from constants of [Pd(NH3)4]2+ and [PdCl4]2-. The calculation results were used to specify the metal-ligands stretching constants and their interactions.

The reaction between trans-[AuF2(pyridine)2]+ and [PhI(pyridine)2]2+ results in the formation of PhIF2 and [Au(pyridine)4]3+. Investigation of the reaction pathway using model Pd and Pt analogs of the gold complex indicate the most likely mechanism is attack by the Au-F onto the I(III), rather than a redox process. This demonstrates that the Au(III)-F fragment can behave in a nucleophilic manner even in a relatively electron poor cationic complex.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 15227-42-6, is researched, Molecular C10H10Cl2N2Pt, about ESR of hot ions: low spin platinum(III) complex ions produced by γ-irradiation, the main research direction is ESR platinum complex gamma irradiation; hot ion platinum complex ESR.Recommanded Product: cis-Dichlorobis(pyridine)platinum(II).

Tervalent Pt complex ions were observed by ESR upon γ-irradiation of both bivalent and quadrivalent complexes. From their g-values, the tervalent complex ions can be classified into 2 types, one axially sym. and the other orthorhombic, the former having typical g-values of 2(g‖) and 2.4(g.perp.), and the latter a g1-value slightly lower than the free electron value of 2.0023. The hyperfine interaction due to 195Pt is 1 order of magnitude larger than that in Co complexes with 3d7 low spin configuration, indicating that the configuration interaction involving 6s-orbital is more important than that for 3d transition metal complexes involving 4s-orbital, and that 5d electrons penetrate deeply into inner shells, resulting in core polarization.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Biological effect of platinum(II) complexes with two different neutral ligands of cis-[PtNH3LCl2] type, published in 1981-08-31, which mentions a compound: 15227-42-6, Name is cis-Dichlorobis(pyridine)platinum(II), Molecular C10H10Cl2N2Pt, Synthetic Route of C10H10Cl2N2Pt.

The effect of Pt complexes on the growth of corn roots was studied. Two types of Pt complexes were used: (1) cis-[PtNH3LCl2], where L = DMSO, C2H4, acetonitrile, pyridine, and benzylamine, and (2) cis-[PtL2Cl2], where L = pyridine, acetonitrile, and benzylamine. The growth-inhibitory effects of all complexes were lower than that of cis-dichlorodiammine platinum [15663-27-1]. The only compound which showed distinct inhibition of mitosis was cis-[PtNH3(PhCH2NH2)Cl2] [79371-82-7]. The antimitotic activity of the Pt diamine complexes was apparently associated with the cis-diamine fragment of the mol.
