Tin selenide, also known as stannous selenide, is an inorganic compound with the formula Sn Se. Tin(II) selenide is a narrow band-gap (IV-VI) semiconductor structurally analogous to black phosphorus. It has received considerable interest for possible applications including low-cost photovoltaics, and memory-switching devices.
The compound precipitates as a brown solid upon the addition of H 2 S to solutions containing tin(IV) species. This reaction is reversed at low pH. It can also be prepared by heating finely ground Sn with excess sulfur. [7] The compound crystallizes in the cadmium iodide motif, with the Sn(IV) situated in "octahedral holes' defined by six ...
Chemical nomenclature, replete as it is with compounds with very complex names, is a repository for some names that may be considered unusual. A browse through the Physical Constants of Organic Compounds in the CRC Handbook of Chemistry and Physics (a fundamental resource) will reveal not just the whimsical work of chemists, but the sometimes peculiar compound names that occur as the ...
