Structural Analyses of tetrathiadodecahydro[3.3.3.3]paracyclophane Complexes with Copper(I) and Silver(I)

Abstract

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. [Ag₂ (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 Cu₄ motifs, in which (CuI)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. Unit cell data: complex 3, monoclinic system, space group P2(1)/n, a = 14.1935(19) Å, b = 13.7879(19) Å, c = 22.222(3) Å, β = 107.888(3)°, Z=4.; complex 4, triclinic system, space group P-1, a = 9.4736(7) Å, b = 12.0619(8) Å, c = 18.0914(10) Å, β = 80.1260(10)°, Z = 2.
