Hybrid orbitals trigonal bipyramidal

Hybridization for trigonal bipyramidal geometries starts with the central atom sp hybridized. The orbitals aligned along the equatorial positions remain as sp hybrids. However, the orbitals along apical positions are pd hybrids. [Pg.61]

Physical Properties. Sulfur tetrafluoride has the stmcture of a distorted trigonal bipyramid, the sulfur having hybrid sp d orbitals and an unshared electron pair (93). The FSF bond angles have been found to be 101° and 187°, and the bond distances 0.1646 and 0.1545 nm (94). [Pg.243]

The orientation of bonds on a central atom of a molecule that has no lone pairs can be any of those listed below. What is the hybridization of the orbitals used by each central atom for its bonding pairs (a) tetrahedral (b) trigonal bipyramidal ... [Pg.253]

An inner atom with a steric number of 5 has trigonal bipyramidal electron group geometry and can be described using s p d hybrid orbitals. [Pg.674]

With a steric number of 5, chlorine has trigonal bipyramidal electron group geomehy. This means the inner atom requires five directional orbitals, which are provided hymsp d hybrid set. Fluorine uses its valence 2 p orbitals to form bonds by overlapping with the hybrid orbitals on the chlorine atom. Remember that the trigonal bipyramid has nonequivalent axial and equatorial sites. As we describe in Chapter 9, lone pairs always occupy equatorial positions. See the orbital overlap view on the next page. [Pg.675]

These compounds are often referred to as hypervalent. The apical bonds in a trigonal bipyramid are described by molecular orbitals constructed from a p-orbital on the central atom and o-bonding orbitals (p- or sp hybrid) on the apical ligands. The molecular orbitals can be drawn as ... [Pg.22]

Both Co2+ and Ni2+ also have the ability to make use of 4s, 4p, and 4d orbitals in another way by forming sp2d2 hybrids in the formation of complexes having a square-based pyramid structure. In fact, trigonal bipyramid and square-based pyramid structures are both observed for [Ni(CN)5J3. ... [Pg.596]

Next we must select a hybridization scheme for the Br atom that is compatible with the predicted shape. It turns out that only sp3d hybridization will provide the necessary trigonal bipyramidal distribution of electron pairs around the bromine atom. In this scheme, one of the sp3d hybrid orbitals is filled while the remaining four are half-occupied. [Pg.235]

The 5d orbital used would be the dz2, which would participate in hybridization with the 5s and three 5p orbitals to give five dsp3 hybrid orbitals disposed towards the vertices of a trigonal bipyramid. The five pairs would assume a trigonally bipyramidal distribution, and it is logical for the fluorine atoms to be as far away from each other as possible to give a linear molecule. The alternative approach would divide the... [Pg.88]

The most common structures of arsenic compounds are tetrahedral and pyramidal, which are similar when the sterically active lone pair is counted. Tetrahedral symmetry holds the potential for chirality and indeed many chiral organoarsenic compounds have been prepared. Arsenic may also use d orbitals for (d-d)n bonding and for hybridization with s2 and p3 orbitals, resulting in trigonal bipyramidal or octahedral structures. In the former the more electronegative substituents occupy the apical position. [Pg.239]

As a second example, let us consider a molecule with the formula AB6 having the symmetry of a trigonal bipyramid Ih. The vector system is shown in Fig. 11-3.2. The set of five hybrid orbitals (or vectors) on A form a basis for a reducible representation of the point group, with the following character ... [Pg.228]

In molecules which are known to have a trigonal bipyramid structure, energy criteria make it unlikely that the first four combinations are important. In PF combination (5) is the most probable and the hybrids are labelled dsp1. In gaseous MoCl it is likely that a combination of (5) and (6) are used, since the 4d and 5p AOa of Mo are close in energy. The hybrid formed from the orbitals in (6) is labelled d sp and the most general form for in MoCl is... [Pg.229]

For each of the following molecules, determine what atomic orbitals on the central atom are allowed by symmetry to be used in the construction of sigma hybrid orbitals, a. NHj (trigonal pyramid) b. BF3 (trigonal plane) c. SF6 (octahedron) d. PF, (trigonal bipyramid)... [Pg.56]

SOLUTION According to Example 3.3, SF4 has a trigonal bipyramidal arrangement of electron pairs. We can construct five equivalent hybrid orbitals by mixing an s-orbital with three p-orbitals and one d-orbital. The result is five sp3d orbitals. [Pg.265]
