Hybridization of Atomic Orbitals I03:24

Hybridization of Atomic Orbitals I

The mathematical expression known as the wave function, ψ, contains information about each orbital and the wavelike properties of electrons in an isolated atom. When atoms are bound together in a molecule, the wave functions combine to produce new mathematical descriptions that have different shapes. This process of combining the wave functions for atomic orbitals is called hybridization and is mathematically accomplished by the linear combination of atomic orbitals. The new orbitals that...

    Main Results:

    • The compound Ni(2)Si(P(2)O(7))(2) was found to be isotypic with related M(2)Si(P(2)O(7))(2) compounds (M = Co, Cd).
    • Nickel atoms are coordinated within NiO(6) octahedra, forming Ni(2)O(10) dimers.
    • These dimers are linked by corner-sharing and phosphate bridges, creating slabs parallel to the (100) plane.
    • Silicon atoms act as bridges connecting these slabs through O-Si-O contacts.

    Conclusions:

    • The detailed crystal structure of Ni(2)Si(P(2)O(7))(2) reveals a layered arrangement of dinickel(II) oxide dimers.
    • The interconnectedness of these layers via silicon-oxygen linkages provides a comprehensive understanding of its framework.
    • This structural information is vital for potential applications in materials science and solid-state chemistry.
