Abstract:

The title compound [Cu4Cl4(TTTA)2](TTTA=1,3,5,7-tetramethyl-2,4,6,8-tetrathiaadamantane, C10H16S4) crystallizes in space group P1 with a=8.5651(11), b=9.0471 (8), c=12.1586(9)Å, α=78.041(7), β=63.321(8), γ=62.552(10)°, V=781. 1 (3) Å3 and Z = 1. The full- matrix least- squares refinement gave R=0.0467 for 2689 observed reflections (I >3.0σ(I)). The crystal structure consists of one-dimensional chains of [Cu4Cl4(TTTA)2]∞, the repeat unit of which is composed of a [Cu4Cl4] stepped cubande with two TTTA ligands. The TTTA ligand only provides two S atoms as two kinds of coordinating atoms, one of which is only used for coordination of Cu atoms in the unit, and the other as a bridge respectively connects two Cu atoms of two neighbour units to form the chains. The configuration around every Cu atom is distored tetrahedron.
