摘要：Two new complexes, [W2Ag2S8(Ca(DMF)6]n 1 and [WAgS4(Na(DMF)3]n 2, have been synthesized and characterized. Single-crystal X-ray analyses show both 1 and 2 have {WAgS4}n anion linear chains, but 1 has a discrete [Ca(DMF)6]2+ cation while 2 is a linear chain. UV-Visible-Near-IR spectroscopy data show that the bandgaps of the two complexes are 1.86 and 1.99 eV, respectively. Electrical conductivity measurements reveal the conductivities of 1 and 2 are 10-7 and 10-8 Scm-1, respectively and they exhibit thermally activated temperature depen- dence, which may be attributed to semiconductors.
