ONE-DIMENSIONAL, 2-DIMENSIONAL AND 3-DIMENSIONAL COPPER(I) AND SILVER(I) COMPLEXES OF 2,11-DITHIA[3.3]PARACYCLOPHANE

Two copper(I) and one silver(I) complex of 2,11-dithia[3.3]paracycloph ane (dtpcp), [Cu2Br2(dtpcp)(MeCN)(2)] 1, [Cu2I2(dtpcp)(2)] . thf 2 and [Ag(dtpcp)(NO3)] 3, have been synthesized and their molecular structu res determined by X-ray crystallography. All three structures contain an infinite network comprising metal cations linked via ditha-bridged paracyclophane and the counter anions. Complexes 1 and 2 are not isost ructural. The repeating dinuclear units [Cu2Br2(dtpcp)(MeCN)(2)] joine d by dtpcp in 1 generate a one-dimensional polymeric chain running par allel to a diagonal axis of the triclinic cell. Complex 2 is a two-dim ensional sheet structure in which a large ring containing six copper a toms includes a tetrahydrofuran molecule as guest inside the open cavi ty. The one-nitrate oxygen bridging two metal centres in complex 3 yie lds a unique three-dimensional channel framework of silver(I) ions. Th e iodine-doped black products of compounds 1-3 at room temperature exh ibited conductivities of 10(-5.9), 10(-5.1) and 10(-4.7) S cm(-1), res pectively.
