Hydrogen telluride is the inorganic compound with the formula H 2 Te.A hydrogen chalcogenide and the simplest hydride of tellurium, it is a colorless gas.Although unstable in ambient air, the gas can exist long enough to be readily detected by the odour of rotting garlic at extremely low concentrations; or by the revolting odour of rotting leeks at somewhat higher concentrations.
Molecular geometry is the three-dimensional arrangement of the atoms that constitute a molecule. It includes the general shape of the molecule as well as bond lengths , bond angles , torsional angles and any other geometrical parameters that determine the position of each atom.
The coordination geometry depends on the number, not the type, of ligands bonded to the metal centre as well as their locations. The number of atoms bonded is the coordination number. The geometrical pattern can be described as a polyhedron where the vertices of the polyhedron are the centres of the coordinating atoms in the ligands. [1]
formula system space group unit cell Å volume density comment reference ammonium hydrotelluride NH 4 TeH at 25°C pressure = 22.7 mmHg, decomposing to H 3 N and H 2 Te then to Te and H 2 [3] ethylmethylimidazolinium hydrotelluride [(C 2 H 5)(CH 3)C 3 N 2 H 2] + TeH − [2] N-butyl-N-methylpyrollidinium hydrotelluride [(C 4 H 9)(CH 3)C 4 NH 8 ...
Hydrogen ditelluride or ditellane is an unstable hydrogen dichalcogenide containing two tellurium atoms per molecule, with structure H−Te−Te−H or (TeH) 2.Hydrogen ditelluride is interesting to theorists because its molecule is simple yet asymmetric (with no centre of symmetry) and is predicted to be one of the easiest to detect parity violation, in which the left handed molecule has ...

The skeletal formula of the antidepressant drug escitalopram, featuring skeletal representations of heteroatoms, a triple bond, phenyl groups and stereochemistry. The skeletal formula, line-angle formula, bond-line formula or shorthand formula of an organic compound is a type of molecular structural formula that serves as a shorthand representation of a molecule's bonding and some details of ...
Some inorganic solids dissociate - or crack - into molecular species heating or upon dissolving, e.g. Aluminium chloride. In such cases it is helpful to depict both the molecular and the nonmolecular forms. Some important chemical species cannot be easily represented with simple pictures, e.g. hydrochloric acid and non-stoichiometric compounds.
