Reference of 14871-92-2, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 14871-92-2, (2,2¡ä-Bipyridine)dichloropalladium(II), introducing its new discovery.
1H NMR spectroscopic identification of binding modes of 2,2?-bipyridine ligands in complexes of square-planar d8 metal ions
The reaction of [M(bpy)]2+ (M = PdII and/or Pt II; bpy = 2,2?-bipyridine) moieties with model nucleobases leads to a variety of products, viz. 1: 1, 1: 2 and 2: 2 (head-tail, ht, or head-head, hh) complexes. By carefully analysing the H5 (H5?) resonances of the bpy ligands, which in all cases occur furthest upfield, and with additional indicators (concentration dependence of H6, H6? resonances; 195Pt-1H coupling constants, if observable; absolute shifts of H5, H5?), it is possible to assign binding situations of bpy ligands, even in multinuclear complexes with several [M(bpy)]2+ entities in different environments present. The analysis presented here is carried out on X-ray structurally established cases of [M(bpy)]2+ complexes, including three new ones, [Pt(1-MeC-N3)2(bpy)](NO 3)2¡¤2.5H2O (5), ht-[(bpy)Pd(N3-1- MeC–N4)2Pd(bpy)](ClO4)2¡¤ 3H2O (16) and ht-[(bpy)Pd(N1-ampy–N2)2Pd(bpy)] (NO3)2¡¤3H2O (17). The data provide a consistent picture, useful for the future assignment of similar bpy complexes in the absence of X-ray structural evidence. The Royal Society of Chemistry 2009.
