A new self-assembled copper(I) complex of 2-thioxo-5H-1,3-dithiolo[4,5-b][1,4]dithiepin-6(7H)-one showing three-dimensional supramolecular networks

The synthesis and structural characterization of a supramolecular copper(I) complex of 2-thioxo-1,3-dithiolo[4,5-b][1,4]dithiepin-6(7H)-one are descri bed. The complex crystallized in the orthorhombic space group Pna2(1) with the cell dimensions a = 12.9124(2), b = 20.7944(2), c = 4.4457(1) Angstrom, V = 1193.70(3) Angstrom(3) and Z = 4. The structure was refined to a final agreement factor R = 0.0295. The C6H4OS5Cu units are connected by bridging iodide atoms to form a ladder structure. The Cu ... Cu separation is 2.988 4(9) Angstrom, and the short S ... S and S ... I contacts interchain lead t o a novel three-dimensional network. (C) 1999 Elsevier Science S.A. All rig hts reserved.
