摘要：

A new copper-antimony sulfide, [C4H12N2](0.5)[CuSb6S10], has been hydrothermally synthesized from binary metal sulfides in the presence of triethylenetetramine and characterized by single-crystal X-ray diffraction, thermogravimetry, elemental analysis, and SQUID magnetometry. The product (M-r = 1158.72) crystallizes in the monoclinic space group P2(1)/n with a = 11.2578(4) Angstrom, b = 12.5259(5) Angstrom, c = 13.9390(7) Angstrom, beta = 102.445(3)degrees, and V = 1919.4 Angstrom(3). The structure consists of cyclic Sb3S63- units in a boatlike conformation, linked by Sb-S bonds to form a complex Sb6S126- building block. Sb-S bonds serve to link Sb6S126- units to four others in a herringbone array, forming a sheet of stoichiometry Sb6S102-, containing 24-membered rings of alternating Sb and S atoms. Pairs of edge-sharing CuS4 distorted tetrahedra form pillars which link Sb6S102- layers together. The interlayer space contains piperazine cations, formed by cyclization of the triethylenetetramine during synthesis. Bond-valence sums are consistent with the presence of antimony(III) and copper(I), requiring complete protonation of the amine.
