Structural analyses of tetrathiadodecahydro[3.3.3.3]paracyclophane complexes with copper(I) and silver(I)

The preparation and X-ray structures of complexes of 2,11,20,29-tetrathia-4e,5,6,7e,8,9,22e,23,24,25e,26,27-dodecahydro[3.3.3.3]cyclophane (2) (tTTDHPCP) with Cu(I), i.e. [Cu2I2(tTTDHPCP)].thf 3, and with Ag(I), i.e. [Ag-2 (tTTDHPCP)(CF3COO)(2)] 4, are reported. The sulfur atoms of compound 2 bind with metals to serve as the bridge in the polymeric structures, while anions interact with other metal atoms forming multi-dimensional structures. Complex 3 is a novel three-dimensional coordination polymer composed of Cu-4 motifs, in which (Cul)(2) forms a square planar unit to link the compound 2 molecules with a THF molecule situated outside the open cavities. In contrast, the Ag atom in complex 4 serves as a bridge for two compound 2 molecules, providing a two-dimensional channel framework.
