  2. Phosphorus pentachloride - Wikipedia

    en.wikipedia.org/wiki/Phosphorus_pentachloride

    Phosphorus pentachloride is the chemical compound with the formula PCl 5.It is one of the most important phosphorus chlorides/oxychlorides, others being PCl 3 and POCl 3.PCl 5 finds use as a chlorinating reagent.

  3. Trigonal bipyramidal molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Trigonal_bipyramidal...

    In chemistry, a trigonal bipyramid formation is a molecular geometry with one atom at the center and 5 more atoms at the corners of a triangular bipyramid. [1] This is one geometry for which the bond angles surrounding the central atom are not identical (see also pentagonal bipyramid), because there is no geometrical arrangement with five terminal atoms in equivalent positions.

  4. Hypervalent molecule - Wikipedia

    en.wikipedia.org/wiki/Hypervalent_molecule

    Hypervalent iodine compounds are useful reagents in organic chemistry (e.g. Dess–Martin periodinane) Tetra-, penta- and hexavalent phosphorus, silicon, and sulfur compounds (e.g. PCl 5, PF 5, SF 6, sulfuranes and persulfuranes) Noble gas compounds (ex. xenon tetrafluoride, XeF 4) Halogen polyfluorides (ex. chlorine pentafluoride, ClF 5)

    Structure of iodine heptafluoride, an example of a molecule with the pentagonal-bipyramidal coordination geometry. In chemistry, a pentagonal bipyramid is a molecular geometry with one atom at the centre with seven ligands at the corners of a pentagonal bipyramid. A perfect pentagonal bipyramid belongs to the molecular point group D 5h.

  6. Phosphoryl chloride - Wikipedia

    en.wikipedia.org/wiki/Phosphoryl_chloride

    Like phosphate, POCl 3 is tetrahedral in shape. [6] It features three P−Cl bonds and one strong P–O bond, with an estimated bond dissociation energy of 533.5 kJ/mol. Unlike in the case of POF 3 , the Schomaker-Stevenson rule predicts appropriate bond length for the P–O bond only if the P–O bond is treated as a double bond, P=O.

  7. Phosphorus trichloride - Wikipedia

    en.wikipedia.org/wiki/Phosphorus_trichloride

    It has a trigonal pyramidal shape. ... PCl 3, like the more popular phosphorus trifluoride, is a ligand in coordination chemistry. One example is Mo(CO) 5 PCl 3.

  8. Molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Molecular_geometry

    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.

  9. Pentagonal planar molecular geometry - Wikipedia

    en.wikipedia.org/wiki/Pentagonal_planar...

    In chemistry, the pentagonal planar molecular geometry describes the shape of compounds where five atoms, groups of atoms, or ligands are arranged around a central atom, defining the vertices of a pentagon. AX 5 E 2
