Manganese(II) diselenide is the inorganic compound with the formula MnSe₂. This rarely encountered solid is structurally similar to that of iron pyrite (FeS₂). Analogous to the description of iron pyrite, manganese diselenide is sometimes viewed as being composed of Mn²⁺ and Se₂²⁻ ions, although being a semiconductor, MnSe₂ is not appropriately described in formal oxidation states.^[1]^[2]

Spectroscopy

The high‐resolution Mn 2p spectra of the MnSe₂ has two distinct peaks at 642.2 and 653.9 electronvolts correspond to the Mn 2p3/2 and Mn 2p1/2 spin–orbit components, respectively. The energy difference (Δ 2p) of 11.7 eV confirms the presence of Mn⁴⁺ ions in the sample. A good correlation was observed with the literature value for the Mn⁴⁺ state.^[3] No peaks for Mn²⁺ ions were observed at 640–641 eV, which confirmed the formation of only the Mn⁴⁺ oxidation state with a d³ electronic configuration. The Se 3d spectra were deconvoluted into two well‐defined peaks (3d5/2 and 3d3/2) at a binding energy of 54.46 and 55.31 eV, respectively. These two peaks confirmed the presence of Se²⁻ ions in MnSe₂.^[4]

Economy of Salt Lake City

Part of Downtown Salt Lake 2005 The economy of Salt Lake City, Utah is primarily service-oriented. While nearby Bingham Canyon Mine (the world's largest open-pit mine) provided a strong source of income during the 19th century, the city has evolved to an economy built on transit hubs, call centers, and seasonal tourism. The 2002 Olympic Winter Games gave a great boost to the area's economy. Many hotels and restaurants were built for the 2002 Olympics, and although many survive, they have suf...
