Synthesis and structure of a novel bis (mu-eta(2)-thianthrene) disilver(I) bis (perchlorate)

摘要

A novel bis(thianthrene)disilver(I)bis(perchlorate), [Ag-2(TA)(2)(ClO4)(2)] (1) (TA = thianthrene), was prepared and characterized by single-crystal X-ray diffraction methods, H-1 and C-13 NMR: IR and UV spectra analysis. Complex 1 is triclinic, space group , a = 9.244(1), b = 9.275(1), c = 8.343(2) Angstrom, alpha = 101.22(1)degrees, beta = 110.63(1)degrees, gamma = 97.15(i)degrees, V = 679.8(2) Angstrom(3), Z = 2, R = 0.028 and R-w = 0.042. The silver is tetrahedrally coordinated to an oxygen of ClO4-, a phenylene ring of one TA, and to two sulfur atoms of the other TA. The average distance of silver to the phenylene ring in complex 1 is 2.55 Angstrom. Both H-1 and C-13 NMR Studies indicate that the silver-phenylene ring bond is broken in acetone solution. The complex 1 is an insulator, while the I-2-doped blue complex shows a new absorption band at 478 nm and an electric conductivity of 5.0 x 10(-4) S cm(-1). (C) 1998 Elsevier Science S.A.
