Benzopyran is a polycyclic organic compound that results from the fusion of a benzene ring to a heterocyclic pyran ring.. According to current IUPAC nomenclature, the name chromene used in previous recommendations is retained; however, systematic ‘benzo’ names, for example 2H-1-benzopyran, are preferred IUPAC names for chromene, isochromene, chromane, isochromane, and their chalcogen ...
The two piperidine ligands in this yellow-colored compound are labile, which allows other ligands to be introduced under mild conditions. For instance, the reaction of [Mo(CO) 4 (piperidine) 2] with triphenyl phosphine in boiling dichloromethane (b.p. ca. 40 °C) gives cis-[Mo(CO) 4 (PPh 3) 2]. This cis-complex isomerizes in toluene to trans ...
They tend to form structurally complex oxyanions by condensation at lower pH values, such as [Mo 7 O 24] 6− and [Mo 8 O 26] 4−. Polymolybdates can incorporate other ions, forming polyoxometalates. [30] The dark-blue phosphorus-containing heteropolymolybdate P[Mo 12 O 40] 3− is used for the spectroscopic detection of phosphorus. [31]

Hydrogen (1 H) has three naturally occurring isotopes: 1 H, 2 H, and 3 H. 1 H and 2 H are stable, while 3 H has a half-life of 12.32(2) years. [3] [nb 1] Heavier isotopes also exist; all are synthetic and have a half-life of less than 1 zeptosecond (10 −21 s). [4] [5] Of these, 5 H is the least stable, while 7 H is the most.
hexasilane Si 6 H 14 or H 3 Si−SiH 2 −SiH 2 −SiH 2 −SiH 2 −SiH 3, 6 silicon atoms and 14 hydrogen atoms, analogous to hexane; Silanes are named by adding the suffix-silane to the appropriate numerical multiplier prefix. Hence, disilane, Si 2 H 6; trisilane Si 3 H 8; tetrasilane Si 4 H 10; pentasilane Si 5 H 12; etc.
In its ground electronic and vibrational state, the nuclei are collinear, and the molecule has a permanent dipole moment estimated to be μ = 0.8 D = 2.7 × 10 −30 C·m. [2] The ground vibrational and electronic (vibronic) state exhibits a simple rigid rotor -type rotational spectrum.
Lithium lanthanum zirconium oxide (LLZO, Li 7 La 3 Zr 2 O 12) or lithium lanthanum zirconate is a lithium-stuffed garnet material that is under investigation for its use in solid-state electrolytes in lithium-based battery technologies.
