Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 15227-42-6, is researched, SMILESS is [Cl-][Pt+2]([N]1=CC=CC=C1)([Cl-])[N]2=CC=CC=C2, Molecular C10H10Cl2N2PtJournal, Bulletin of the Chemical Society of Japan called ESR of hot ions: low spin platinum(III) complex ions produced by γ-irradiation, Author is Amano, Chikara; Fujiwara, Shizuo, the main research direction is ESR platinum complex gamma irradiation; hot ion platinum complex ESR.Formula: C10H10Cl2N2Pt.
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.
