You have a neutral, 4-coordinate macrocyclic ligand that binds to Ni(II). When a weakly-coordinating perchlorate ion (CIO4-2) is the anion in solution, it produces a red-colored diamagnetic low-spin d8 complex.

Atomic Structure

The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.

Shape of the D Orbital

Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
