 Title    Nachweis eines doppelt verbrückenden MoS 4 2_ -Liganden zwischen Fe-Zentren mit dem Resonanz-Raman-Effekt und einfache Darstellung von [(C6H5)4P]2[Cl2FeS2MoS2FeCl2] Identification of a Doubly Bridging M0S4 2-Ligand between Fe-Centers by the Resonance Raman Effect and a Simple Preparation of [(C6H5)4PMCl2FeS2MoS2FeCl2]  
 Abstract    A very simple preparation method for the complex [Cl2FeS2MoS2FeCl2] 2 ~ is described and Fe 2+ /MoS4 2_ interactions are discussed. The Resonance Raman Effect is a sensitive probe for the doubly bridging MoS4 2_ ligand.

 Title    Synthesis and Structure of a Tetranuclear Nickel Complex of a 40-Membered Macrocyclic Octaamine-Tetrathiophenolate Ligand  
 Abstract    The syntheses and characterization of tetranuclear Ni complexes [(L2)Ni4][C104]4 (3) and [(L2)Ni4(NCS)4] (4) of a 40-membered macrocyclic octaamine-tetrathiophenolate ligand (L2)4-are described. Single-crystal X-ray structure analysis of 4 reveals well-separated molecules of the tetranuclear isothiocyanate complex [(L2) N i 4(NCS)4]. The four Ni" centers are arranged in binuclear [N2N i(^ 2-SR)2N iN 2(NCS)2] subunits containing distorted square-planar NiN 2S2 and distorted octahedral NiN 2S2(NCS)2 sites. The fact that the two isothiocyanate groups at the octahedral Ni site are in trans positions can be ascribed to the large ring size of the macrocycle.

 Title    Complexes of 1,2,4-Triazoles, VII [1] Preparation and Vibrational Spectra of 4,4'-Bi-l,2,4-triazole and Some of its Complexes with Transition Metal(II) Thiocyanates  
 Abstract    The preparation and characterization of 4,4'-bi-l,2,4-triazole is described. The com-pound is a strong, polydentate, polynucleating nitrogen donor. Two complexes, M(btr)2(NCS)2H20 M = Co, Ni, are described. The vibrational spectra of ligand and complexes are compared. A structure for the complexes is proposed.
