 Title    Synthese und Strukturuntersuchungen von Iodocupraten(I) XIV. Iodocuprate(I) mit /f-(7-gebundenen Kationen [1] Synthesis and Structure Investigations of Iodocuprates(I) XIV. Iodocuprates(I) with «-er-Bonded Cations [1]  
 Abstract    Reactions o f Cul with N-methylpyrazinium iodide, (pyr)I, N-methyl-4,4'-bipyridinium iodide, (bp 4)1 and N-methyl-2,2'-bipyridinium iodide, (bp 2)1, in organic solvents led to three novel types o f copper(I) complexes o f stoichiometries (pyr)Cu2I3, (bp4)C u3I4 and (bp2)C u2I3. In all o f them the cations are n-a-bonded to copper(I) through donation o f their unshared electron pairs. (pyr)Cu2I3 crystallizes with an ionic structure (trigonal, R 3 c , hexagonal axes a -3053(2), c = 671.9(3) pm, Z = 18). Polymeric cations i[((pyr)C uI3/3)3]3+ and anions i[C u I4/2]-form parallel rod packings. The structure m otif o f the cations can be described as a columnar part o f the ß-Cu\ structure in which the copper and iodine atom s are also arranged to Cu3I3 rings. The crystal structure o f (bp4)C u3I4 (triclinic, P I, a = 938.8(2), b = 980.0(4), c = 1070.1(3) pm, a = 73.56(3), ß = 75.79(2), y = 89.50(3)°, Z = 2) is built up by uncharged chains i[(C uI4/3)(CuI3 3I1/2)((bp4)C uI2/3I1;2)]. The trinuclear units (bp4)C u3I4 are connected via com ­ mon iodide edges. The copper halide connection m otif o f the polymeric com pound has some features in com m on with the "stair" and "cube" structures o f adducts o f Cul with unidentate, neutral P-, As-or N-bases. The com pound (bp2)C u2I3 (m onoclinic, P 2 ,/«, a = 1054.0(2), b = 1034.8(3), c = 1512.6(3) pm, ß = 108.10(2)°, Z = 2) has a structure, in which two edge-sharing (C ul4,2)-tetra-hedra and two approximately planar (C u l2/2(bp2))-units form tetranuclear molecules (bp2)2Cu4I6. These are linked to chains with a "stair" m otif by intermolecular Cu • • • I contacts.

 Title    Binding of Cations to 4 f Metal Ions : Preparation and Properties of Lanthanide(III) Complexes Containing the Phenelzinium(l+) Cation as a Ligand  
 Abstract    Treatment o f Ln2(S 0 4)3 • nH 20 (Ln = La, Ce, Pr, Nd, Sm. Eu, Gd ; n -8, 9) with phenelzine dihydrogen sulfate, (phzH2) S 0 4, in 1 N H2S 0 4 yields polymeric complexes with the general formula [L n (S 0 4)2(H 20) 2(phzH)], which contain the phzH+ cation as a ligand. The compounds have been characterized by elem ental analyses, X-ray powder patterns, thermal methods, magnetic susceptibilities and spectroscopic (IR, Raman, electronic diffuse reflec­ tance and solid-state emission f -f spectra) studies. The prepared complexes most probably consist of 7-coordinated units, formed by four bridging bidentate sulfato groups, two terminal aqua m olecules and one cationic phzH+ ligand.
