In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called 2-Picolinoylpyrrole: A new entry to metal-complexing agent, published in 2006-07-05, which mentions a compound: 39901-94-5, mainly applied to palladium platinum picolinoylpyrrole preparation structure; crystal structure palladium platinum picolinoylpyrrolato complex, Formula: C6H5Cl2NO.
The Pd(II) and Pt(II) complexes, [ML2], of 2-picolinoylpyrrole (HL) were synthesized and the 2:1 square-planar coordination, wherein each pyrrole and pyridine moieties are in trans positions, resp., were characterized by x-ray single-crystal analyses.
In some applications, this compound(39901-94-5)Formula: C6H5Cl2NO is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
