A spectrochemical series is a list of ligands ordered by ligand "strength", and a list of metal ions based on oxidation number, group and element.For a metal ion, the ligands modify the difference in energy Δ between the d orbitals, called the ligand-field splitting parameter in ligand field theory, or the crystal-field splitting parameter in crystal field theory.

In chemistry, aluminium(I) refers to monovalent aluminium (+1 oxidation state) in both ionic and covalent bonds. Along with aluminium(II), it is an extremely unstable form of aluminium. While late Group 13 elements such as thallium and indium prefer the +1 oxidation state, aluminium(I) is rare.
This equilibrium serves to confirm that the linear nitrosyl ligand is, formally, NO +, with nitrogen in the oxidation state +3 NO + + 2 OH − ⇌ NO 2 − + H 2 O. Since nitrogen is more electronegative than carbon, metal-nitrosyl complexes tend to be more electrophilic than related metal carbonyl complexes. Nucleophiles often add to the ...
This property is illustrated by the stability of some metal ammine complexes in strong acid solutions. When the M– NH 3 bond is weak, the ammine ligand dissociates and protonation ensues. The behavior is illustrated by the respective non-reaction and reaction with [Co(NH 3) 6] 3+ and [Ni(NH 3) 6] 2+ toward aqueous acids.
[1] [2] In this type of interaction, electrons from the metal are used to bond to the ligand, which dissipates excess negative charge and stabilizes the metal. It is common in transition metals with low oxidation states that have ligands such as carbon monoxide, olefins, or phosphines.
The vast majority of compounds, including all aluminium-containing minerals and all commercially significant aluminium compounds, feature aluminium in the oxidation state 3+. The coordination number of such compounds varies, but generally Al 3+ is either six- or four-coordinate. Almost all compounds of aluminium(III) are colorless. [2]
