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 Hydroxy complexes of platinum(II) and palladium(II), published in 1972, which mentions a compound: 15227-42-6, Name is cis-Dichlorobis(pyridine)platinum(II), Molecular C10H10Cl2N2Pt, COA of Formula: C10H10Cl2N2Pt.
The preparation of hydroxy bridged complexes, [M2(OH)2-L4][BF4]2, where M = Pt and L = Et3P, Ph3P or py, or where M = Pd and L = Ph3P, is described. The structures are unambiguously established by ir, NMR, and x-ray crystallog. studies. The complexes are stable and resist bridge cleavage by tertiary phosphines under conditions which easily cleave analogous chloro bridged complexes.
There is still a lot of research devoted to this compound(SMILES：[Cl-][Pt+2]([N]1=CC=CC=C1)([Cl-])[N]2=CC=CC=C2)COA of Formula: C10H10Cl2N2Pt, and with the development of science, more effects of this compound(15227-42-6) can be discovered.
