Crystal structure, physical properties and Pt-195 NMR characterization of Pt(bipy)Br

The complex dibromobipyridylplatinum(II), Pt(bipy)Br2, crystallizes in the monoclinic space groupC2/c witha = 17.262(5) Å,b = 9.388(2) Å,c = 7.557(2) Å, β = 113.47(2)∘, andZ = 4. The complex is isomorphous to the monomeric copper derivative, Cu(bipy)Br2. The195Pt NMR spectrum shows the typical line broadening effect caused by coordinated nitrogen-14. The complex resonates at −1897 ppm with a half-height peak width of 1300 Hz. The structure is compared with the analogous structures Pt(bipy)(X)2 (X = Cl and I) and Pd(bipy)Br2.
