Abstract

The new compound Hg?2.8KMo12S14 was synthesized by diffusing mercury into the metastable KMo12S14 compound at 350 °C. Its crystallographic structure, solved from single-crystal X-ray diffraction, shows that the Mo-S framework is maintained during the synthesis. It is based on Mo12S14S6 units interlinked via Mo-S bonds as in the parent compound. The mercury forms linear chains with Hg-Hg distances of about 2.72 Å in the tunnels delimited by the Mo12S14S6 units. Superconductivity was observed below 2.5 K by electrical resistivity and magnetic susceptibility measurements.

Sulfur Bohr ModelThe number of electrons in each of Sulfur's shells is 2, 8, 6 and its electron configuration is [Ne] 3s2 3p4. In its elemental form, sulfur has a light yellow appearance. The sulfur atom has a covalent radius of 105 pm and a Van der Waals radius of 180 pm. In nature, sulfur can be found in hot springs, meteorites, volcanoes, and as galena, gypsum, and epsom salts. Sulfur has been known since ancient times but was not accepted as an element until 1777, when Antoine Lavoisier helped to convince the scientific community that it was an element and not a compound.

Mercury

Mercury Bohr ModelSee more Mercury products. Mercury (atomic symbol: Hg, atomic number: 80) is a Block D, Group 12, Period 6 element with an atomic weight of 200.59. The number of electrons in each of mercury's shells is 2, 8, 18,32, 18, 2 and its electron configuration is [Xe] 4f14 5d10 6s2. The mercury atom has a radius of 151 pm and a Van der Waals radius of 209 pm. It is named after the planet Mercury and often referred to as "quicksilver" due to its appearance as a silvery liquid. Mercury has low melting and boiling points. It is a poor conductor of heat, but a fair conductor of electricity. Mercury is found both as a free element and in cinnabar, corderoite, and livingstonite ores.
