 Abstract    an Tetracarbonyl(organoelement IV a-phosphin)eisen(0)-Komplexen °'Fe and 119Sn Mössbauer Studies on Tetracarbonyl(organoelement IVa-phosphine)iron(O) Complexes J ü r g e n E n s l i n g , P h i l i p p G ü t l i c h Mössbauer Studies, Iron Carbonyl Derivatives 57Fe and 119Sn Mössbauer effect measurements were performed on a series of complexes of the type (CO^FeL with L being organoelement(IVa)-phosphine, [(C H 3)3C]3_nP [E (C H 3)3] n (n = 0,l,2,2; E = Si, Sn), to gain some insight into the nature of the phosphorous-ele-m ent(IVa) bond as well as the iron-nearest neighbour bond. The results of the Mössbauer measurements are in contradiction with the widely discussed presence of (p->d)n inter­ action in the phosphorous-element(IVa) bond. In accordance with N M R and vibrational spectroscopic studies they rather suggest that (p-^-d)^ interaction be of little importance.

 Abstract    Electroreduction of N i(II) and C o(II) lias been carried out in aqueous mixtures of formamide, acetamide and urea. Electrode kinetics in terms of theories of irreversible waves have been studied. After calculating the rate constants by D e l a h a y 1 and K o u ­ t e c k y 2 treatments separately their variation with electrode potential has been used to calculate the product 'ana\ The rate constants and 'ana' calculated from two different approaches show remarkable agreement.

 Title    Kooperative Jahn-Teller-Wechselwirkungen im HgCu(NCS)4 Cooperative Jahn-Teller Coupling in HgCu(NCS)4 Crystals  
 Abstract    C l a u s F r i e b e l und M a r i a J. G o n z a l e z G a r m e n d i a Mercury-tetraisothiocyanato-cuprate(II), E P R , Exchange Narrowing, Structural Details From E P R measurements on HgCu(NCS)4 crystals (space group Dj^-Pbcn) a coupling of four differently orientated tetragonally elongated CUN4S2 octahedra with very long axial distances can be deduced. Two at a time of these polyhedra with differently orientated C u -N axes are ferrodistortively ordered in layers 11(001). The Cu2+ ions of adjacent ferrodistortive layers are coupled in a disturbed type of antiferrodistortive order. The angle 2 y — 113° between the CuN4 planes of the ferrodistortive layers, resulting from the spectroscopic data, is in approximative agreement with 2 y = 119° found by X-ray structure determination. A strong exchange narrowing of the E P R line is observed in the (010) plane in an angle of ß = + 22° against the a-axis. From this exchange direction corresponding to the projection of one of the C u -N axes on the (010) plane, conclusions can be drawn concerning the orientation of the magnetic dipoles connected with the spin moments of the coupled Cu2+ ions.

 Title    Quenchable High Pressure Phases of GdYbS3 High Pressure Phases, Crystal Structures  
 Abstract    Three new modifications of G dY bS 3 can be retained metastably, after quenching from high pressure and temperature. The Guinier powder data is presented and indexed. The three modifications include a cubic defect Th3P 4-type phase with a — 8.310(2) Ä, an orthorhombic A-type phase with a = 7.279(4) A, b — 15.119(6) Ä and c = 3.875(3) A, and an orthorhombic U 2S3-type phase with a = 10.603(5) A, b = 3.869(3) Ä and c = 10.385(5) Ä. Structural relationships between the present group of structures and the structures of the rare earth sulfides with formula Ln2S3 are discussed.
