摘要：
Dark-red octahedrally shaped crystals of NaAg3S2 could be obtained by the rection of NaAg(CN)2 and NaCN in a stream of hydrogen sulfide at 630 K. NaAg3S2- crystallizes cubic, a = 12.358(1) angstrom, space group Fd3BARm, Z = 16. The structure was determined from four-circle diffractometer data. NaAg3S2 contains the anionic cluster [Ag6S4]2-. The structure can be traced back to the spinel structure typ. An extended Huckel calculation for the cluster anion, which is considered to be isolated, shows weak bonding silver-silver interactions. NaAg3S2 is diamagnetic at room temperature.
