 Abstract    III. Iodocuprate(I) mit isolierten Ketten oc[Cu2l3 ]_ bzw. i[C u 3l 4 ]_ [1] Syntheses and Structure Analyses of Iodocuprates(I), III. Iodocuprates(I) with Isolated Chains [CU2I3]"" or 4 [C u 3I4]~ N-Methylpyridinium-triiododicuprate(I), C6H8NCu2I3, methyltriphenylphosphonium-tetra-iodotricuprate(I), (C6H5)3CH3PCu3I4 and tetrapropylammonium-tetraiodotricuprate(I), (C3H7)4NCu3I4 were obtained by reacting Cu with I2 and C6H8NI, (C6H5)3CH3PI or (C3H7)4NI in acetone. The crystal structures of these compounds are built up by the cations and isolated chains of edge or face sharing Cul4-tetrahedra: [C6H8N ]+ « [(C u I^ I ^)^ -, [(C6H5)3CH3P] + oc[(CuI1/2I2/3I1/4)2 (CuI2/3I2/4)]_ and [(C3H7)4N ]+ i[(C u I3/3I1/2)2 (CuI3/3)]~. There are very short C u -C u distances of 246.1(5) and 250.3(5) pm in (C3H7)4NCu3I4 produced by face sharing of Cul4-tetrahedra.

 Title    Synthese und Strukturuntersuchungen von Iodocupraten(I) VI. Iodocuprate(I) mit zweikernigen Anionen [CU2I4]2-und [Cu2I6]4-[1] Syntheses and Structure Analyses of Iodocuprates(I) VI. Iodocuprates(I) with Dinuclear Anions [Cu2I4]2-and [Cu2I6]4-[1]  
 Abstract    Bis(dipyridiniom ethan)-di-,a-iodotetraiododicuprate(I), [Py2CH 2]2[Cu2I6] and two m odifica­ tions o f bis(tetraphenylphosphonium)-di-^-iodo-diiododicuprate(I) were obtained by reacting Cu with I2 and [Py2C H 2]I2 or [PPh4]I in acetone. The crystal structures o f these com pounds are built up by the cations and the binuclear anions: edge sharing C ul4-tetrahedra in [Cu2I6]4~ and edge sharing, nearly trigonal planar C u l3-units in [Cu2I4]2~. W hereas the Cu2I4 anions (-A) are centrosym m etric and almost planar, the anions (-B) are folded about the bridging I---I contact. The anions [Cu2I6] are in intimate contact with the I -C interactions.

 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.
