    Description / Table of Contents: Amidinocomplexes of Molybdenum (V) and Rhenium (V). Crystal Structure of [Cl4Mo{i-Prop-NC(Cl) N-i-Prop}]Molybdenum pentachloride and rhenium pentachloride, respectively, react with di-isopropylcarbodiimide in CCl4-suspensions forming the monomeric amidino complexes [Cl4M{i-prop-NC(Cl)N-i-prop}] (M = Mo, Re). According to the i.r. spectra the C—Cl-amidino ligand is bonded as a chelate. The molybdenum complex is characterized by an X-ray structure determination. It crystallizes in the tetragonalic space group I41/a with 8 formula units in the unit cell (1538 independent, observed reflexions, R = 0.051) with the lattice constants a = 1119 and b = 2332 pm.
    Notes: Molybdänpentachlorid bzw. Rheniumpentachlorid reagieren mit Di-isopropylcarbodiimid in CCl4-Suspensionen unter Bildung der monomeren Amidinokomplexe [Cl4M{i-Prop-NC(Cl)N-i-Prop}] (M = Mo, Re). nach den IR-Spektren ist der C-Chlor-amidinoligand als Chelat gebunden. Der Molybdänkomplex wurde durch eine röntgenorgraphische Strukturanalyse charakterisiert. Er kristallisiert in der tetragonalen Raumgruppe 141/a mit 8 Formeleinheiten pro Elementarzelle (1538 unabhängige, beobachtete Reflexe, R = 5,1%) mit den Gitterabmessungen a = 1119 und b = 2332 pm.

    Description / Table of Contents: Crystal Structure of [Cl4P{i-Prop-NC(Cl)N-i-Prop}]The monomeric di-isopropylcarbodiimide complex [Cl4P{i-Prop-NC(Cl)N-i-Prop}] crystallizes in the monoclinic space group C2 with 4 formula units in the unit cell and with the lattice constants a = 1391.2(2), b = 708.6(1), c = 1463.5(2) pm and β = 95.76(1)°. The structure was refined to an R-value of 0.026 (2084 independent, observed reflexions). Main parts of the IR and Raman spectrum of the compound are discussed.
