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.
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 ...

With three terminal oxide groups, nitrate can in principle bind metals through many geometries. Even though the ligand is written as MNO 3, the oxygen atoms are invariably coordinated. Thus, monodentate nitrate is illustrated by [Co(NH 3) 5 NO 3] 2+, which could also be written as [Co(NH 3) 5 ONO 2] 2+. Homoleptic metal nitrate complexes ...
Compounds of the metallic elements usually form simple aqua ions with the formula [M(H 2 O) n] z+ in low oxidation states. With the higher oxidation states the simple aqua ions dissociate losing hydrogen ions to yield complexes that contain both water molecules and hydroxide or oxide ions, such as the vanadium(IV) species [VO(H 2 O) 5] 2+. In ...
They are both σ- and π-donors. Chloride is commonly found as both a terminal ligand and a bridging ligand. The halide ligands are weak field ligands. Due to a smaller crystal field splitting energy, the homoleptic halide complexes of the first transition series are all high spin. Only [CrCl 6] 3− is exchange inert.
Seven chloride ligands have Pb-Cl distances of 280–309 pm. Two chloride ligands are more distant, with a Pb-Cl distances of 370 pm. [13] In some cases a different definition of coordination number is used that includes atoms at a greater distance than the nearest neighbours.
