Abstract The structures of the olefinic complexes of platinum(II) withcis-but-2-en-1,4-diammonium, [PtCl3(C4H12N2)]+, and withcis-pent-2-enylammonium, [PtCl3(C5H12N)], the first one as its chloride, have been determined by single-crystal X-ray methods. The compounds form yellow monoclinic crystals, witha=11.238(3),b=12.234(4),c=7.769(1) Å, β = 112.99(2) ° anda= 11.530(3),b=9.037(3),c= 10.067(3) Å, β=105.50(2) °, respectively; both crystallize in the space groupP21/c withZ=4. The structures, solved by standard methods, have been refined anisotropically by full-matrix least-squares methods, both toR=0.040, on, respectively, 1808 and 1849 independent reflections collected by counter methods. In both complexes, platinum is four-coordinate to the three chlorine atoms and the double bond of the olefinic ligand. The structures are discussed, and comparison with the analogous platinum(II)-olefin complexes with the trans isomers of the olefinic ligands is made.
