✦ Synopsis


Zentralinstitut fur Molekularbiologie der Akademie der Wissenschaften dcr UDK, Berlin-Buch and Friedrich-Schillcr-Universitat, Jcnn Crystal and Molecular Structure of Bis(N-[pyrid-e-yl] -1 -imino -2carbethoxy -3 -ox0 -butan-2 -ido) -palladium (11) The crystal ant1 molecular structure of the title compound has been determined by X-ray diffraction techniques. It crystallizes in the orthorhombic space group Pbca with 4 formula units C,4H,8N40,Pd in the unit cell. The lattice constants are a = 17.259, b = 19.070, and c = 7.480 A. The structure was solved by the heavy atom technique and refined by least-squares calculations t o the conventional R = 0.057. The coordination splierc of palladium as well as the molecular geometry of the ligands arr discussed in the paper. Die Kristall-und Molekulstruktur der Titelverbindung wurden niit Hilfe der Rdntgenkristallstrukturanalyse bestimmt. Die Verbindung kristallisiert in der orthorhonibischen Raurngruppe Pbca mit 4 Formrleinhriten C,4H,,N40,Ptl in-der Elementarzrlle. Die Gitterkonstantrn sintl a = 17.259, b = 19.070 und c = 7.480 A. Die Strulitur wurde mit der Schweratomtrchnik gelost untl niit tier Methode der kleinsten Quadrate bis zum R-W-ert von 0.057 verfeinert. Die Koortlinatioiissphirr und die molekulare Geometrir der Liganden werden in der Arbeit diskutiert.
