Selenostannates have been recently investigated for their thermoelectric properties. The conversion of waste heat into electrical energy could prove to be highly beneficial to modern society. Research in our group has been focused on incorporating selenostannates into extended networks. Samples are prepared by mixing stoichiometric ratios of each element in fused quartz tubes. The samples are then heated to 750 degrees Celsius using a computer controlled furnace for two weeks. Single crystals are selected via optical microscopy and examined by SEM-EDX to determine approximate stoichiometry. Promising crystals are examined by single crystal X-ray diffraction. Results will be presented on reactions that produced single crystals of compounds containing copper, iron, tin, and selenium. A discussion of the physical properties of these materials will also be included.
