Zwei neue Modifikationen von [P(C6H5)4]2[Cu2I4]Bei der Reaktion von granuliertem Kupfer mit Iod und [P(C6H5)4]I in trockenem Aceton unter Stickstoffatmosphäre wurden Einkristalle von zwei neuen Modifikationen von [P(C6H5)4]2[Cu2I4] erhalten. Sie kristallisieren monoklin, Raumgruppe P21/n (Nr. 14), a = 11.550(6), b = 7.236 (2), c = 27.232 (13) Å, β = 98.13(3)°, V = 2253(2) Å3 und Z = 2 ([P(C6H5)4]2[Cu2I4]-C) bzw. Raumgruppe Cc (Nr. 9), a = 17.133(5), b = 15.941(5), c = 18.762(6) Å, β = 114.02(1)°, V = 4681(3) Å3 und Z = 4 ([P(C6H5)4]2[Cu2I4] -D). In diesen Verbindungen liegen dimere di-μ-iodo-diiodocuprat(I)-Einheiten vor, die planar (C) bzw. gewinkelt (D) sind.
Notes:
Single crystals of two new modifications of [P(C6H5)4]2[Cu2I4] were obtained by reaction of granulated copper with iodine and [P(C6H5)4]I in dry acetone under nitrogen atmosphere. They crystallise monoclinically, space group P21/n (No. 14), a = 11.550(6), b = 7.236(2), c = 27.232(13) Å, β = 98.13(3)°, V = 2253(2) Å3, and Z = 2 ([P(C6H5)4]2[Cu2I4]-C), and space group Cc (No. 9), a = 17.133(5), b = 15.941(5), c = 18.762 (6) Å, β = 114.02(1)°, V = 4681(3) Å3, and Z = 4 ([P(C6H5)4]2[Cu2I4]-D), respectively. In these compounds the [CuI2]- anions form dimers di-μ-iodo-diiodocuprate(I), which are either planar (C) or folded (D).
