    Description / Table of Contents: The Crystal Structure of Tris(N,N-Diethyl-N′-benzoylselenoureato)indium(III)In(C12H15N2OSe)3 crystallizes in the monoclinic space group P21/c. The cell parameters are a = 11.792(2), b = 36.797(4), c = 18.574(2) Å, β = 92.15(2)° and Z = 4. The structure was solved with Patterson and direct methods and was refined to a final R-value of 3.41%. The asymmetric unit contains two complex molecules. The indium atoms are bidentally coordinated by three N,N-Diethyl-N′-benzoylselenourea molecules to form distorted octahedra with facial arrangement of the selenium and oxygen donor atoms. The chelate rings diverge strongly from planarity. The In—Se bond lengths vary from 2.643(1) to 2.657(1) Å, the In—O bond lengths from 2.179(4) to 2.203(4) Å, respectively.
    Notes: In(C12H15N2OSe)3 kristallisiert in der monoklinen Raumgruppe P21/c mit den Gitterkonstanten a = 11,792(2), b = 36,797(4), c = 18,574(2) Å, β = 92,15(2)°, Z = 4. Die Struktur wurde mit Patterson und Direkten Methoden gelöst und bis zu einem R-Wert von 3,41% verfeinert. In der asymmetrischen Einheit befinden sich zwei In(C12H15N2OSe)3-Komplexmoleküle. Jeweils drei N,N-Diethyl-N′-benzoylseleno-harnstoff-Moleküle sind bidental über Selen- und Sauerstoffatome an die Zentralatome koordiniert. Das Koordinationspolyeder ist ein verzerrter Oktaeder mit facialer Anordnung der Donoratome. Die Chelatringe weichen deutlich von der Planarität ab. Die In—Se-Abstände in den beiden Oktaedern liegen zwischen 2,643(1) und 2,657(1) Å, die In—O-Abstände variieren von 2,179(4) bis 2,203(4) Å.
