	Title	Olefin-, Aromaten-und Allylkomplexe des Vanadiums aus Vanadocen [1] Olefine, Arene, and Allyl Complexes of Vanadium from Vanadocene [1]
	Abstract	Vanadocene (Cp2V) was reduced with potassium metal in tetrahydrofuran (THF) to give a 1:1 adduct K[Cp2V] which has been isolated as [K(THF)(Et20)][Cp2V]. The reactions of this compound with various molecules (L) capable of functioning as ligands were investigated. They cause the liberation of KCp and the formation of several new organovanadium compounds. The products of these reactions were: [K(THF)2 5][CpVCsHi2] for L = butadiene (C4H6), [K(THF)i.5][CpVC6H5P(C6H5)2] for L = P(C6H5)3, CpV(C4H6)P(CH3)3 for L = mixture of C4H6 and P(CH3)3. Vanadocene was reacted with allyllithium to yield LiCp and [LiTMEDA][CpV(C3H5)2] (TMEDA =: (CH3)2NCH2CH2N(CH3)2), which was transformed via allylbromide to CpV(C3Hö)2. Structures and reactivities of these new organovanadium complexes are discussed. I. Einführung Unlängst berichteten wir in Übersichtsaufsätzen [2, 3] zusammenfassend über eine von uns ent-wickelte Synthesemethode, durch die reaktive Über-gangsmetall-Olefin-und Alkalimetall-Übergangs-metall-Olefin-Komplexe des Nickels, Cobalts und Eisens auf einfache Weise zugänglich geworden sind, z.B. mit Ethen als Olefin: Et20 Cp2Co + K + 2 C2H4 • CpCo(C2H4)2 + KCp THF Cp2Co + 3K + 4C2H4 • K[Co(C2H4)4] + 2 KCp THF Cp2Fe + 2 Li + 2 C2H4 Li[CpFe(C2H4)2] + LiCp Wir haben nun überprüft, ob sich dieses Synthese-prinzip, das auf der reduktiven Ablösung der Cp-Ringe von den entsprechenden Metallocenen mittels Alkalimetall in Gegenwart von Olefinen beruht, auch auf das elektronenärmere Vanadocen über-tragen läßt. Überdies war zu klären, ob neben Olefinen auch andere Komplexbildner wie Kohlen-monoxid oder Phosphane oder gar Mischungen von Komplexbildnern eingesetzt werden können. Hier-über sowie über einen zweiten Synthese weg, der

	Title	Crystal Structure Investigation of Two Polymeric Chromium(III) Azide Complexes; KCr(pyridine)4(N3)4 and RbCr(pyridine)3(N3)4. A Structure Containing /i( 1,3) and //(1,1,3) Bridging Azido Ligands between Chromium and Rubidium Centered Polyhedra
	Abstract	The structures of two polymeric complexes of chrom ium (III) azide with pyridine, KCr(py)4(N 3)4 (1), and RbCr(py)3(N 3)4 (2), were determined by X-ray crystallography. Crystal data: 1, C20H 20N 16CrK, monoclinic, space group C2/c, a = 1611.2(5), b = 1050.6(3), c = 1609.0(5) pm, ß -91.69(3)°, Z = 4 and Rw = 0.037 for 923 diffractometer data; 2, C l5H 15N 15CrRb, monoclinic, space group P 2 Jn, a = 1311.9(3), b = 1139.0(4), c = 1523.3(4) pm, ß = 109.39(2)°, Z = 4 and Rw = 0.046 for 2336 data. The crystal structure of 1 contains six-coordinated chromium and potassium cations with two pyridine ligands and four y«(l,3) bridging azido groups forming a three-dimensional net work structure. The chromium atoms are trans-coordinated by the pyridine ligands, whereas the potassium cations are m -coordinated. The polymeric complex 2 features di-//(l,l,3) azido bridged C rR bN 2 rings, distorted octahedral chromium(III) coordination geometry, seven-coordinated rubidium, and di-//(l,3) azido bridges which link the binuclear RbCr(pyridine)3(N 3)2 moieties into infinite chains parallel to the b axis.

	Title	Magnesium Bis[D(-)-Mandelate] Dihydrate and Other Alkaline Earth, Alkali, and Zinc Salts of Mandelic Acid
	Abstract	, and zinc D(-)mandelates have been prepared from the parent mandelic acid and equivalent quantities (1:1 / 2:1) of the corresponding metal hydroxides in water. Colourless polycrystalline products are obtained from the aqueous solutions by evaporation of the solvent. The alkali, ammonium and strontium salts are anhydrous, the calcium and barium salts are monohydrates, the magne sium salt is a dihydrate, and the zinc salt a trihydrate. The crystal and molecular structure of the magnesium salt has been determined by single crystal X-ray diffraction methods (mono clinic, space group P2i, Z = 2). The lattice contains isolated complexes with hexacoordinate magnesium atoms chelated by two mandelate anions through one of their carboxylate oxygen atoms and the alcoholic hydroxyl group. Two water molecules in cis position are completing the octahedral coordination sphere. [MgtQITO^MfTO^] is thus a true mononuclear magnesium complex. Its stability and non-hygroscopic properties suggest its use as a magnesium and/or mandelate drug.
