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. When perchlorate is replaced by two thiocyanate ions, (SCN-), the Ni-macrocycle complex turns violet and has two unpaired electrons. Predict what has happened to the geometry

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.
