Abstract
Bis(dipyridiniomethan)-di-μ-iodotetraiododicuprate(I), [Py2CH2]2[Cu2I6] and two modifications of bis(tetraphenylphosphonium )-di-μ-iodo-diiododicuprate(I) were obtained by reacting Cu with I2 and [Py2CH2]I2 or [PPh4]I in acetone. The crystal structures of these com pounds are built up by the cations and the binuclear anions: edge sharing Cul4-tetrahedra in [Cu2I6]4- and edge sharing, nearly trigonal planar Cul3-units in [Cu2I4]2-. Whereas the Cu2I4 anions (-A ) are centrosymmetric and almost planar, the anions (-B) are folded about the bridging I···I contact. The anions [Cu2I6] are in intimate contact with the cations via short intermolecular I···N and I···C interactions.Keywords
