Webligand-field theory formulate an explanation of the weak absorption bands. Being a weak π-donor, H 2O is a weak field ligand, which leads to a high spin Fe 3+ (d5) octahedron ion with the electronic configuration t 2g (*)3 e g* 2. This electronic configuration means that the HOMO-LUMO transition will be both spin forbidden WebLigands can be arranged in a so-called spectrochemical series in order from strong π acceptors (correlated with low spin, strong field, and large δ values) to strong π donors (correlated with high spin, weak field, and small δ values) as follows: CO, CN − > 1,10-phenanthroline > NO 2 − > en > NH 3 > NCS − > H 2 O > F − > RCOO − ... WebOct 19, 2015 · Briefly for weak ligand, low splitting of the orbital occurred.

WebThus, iodide is a weak field ligand and gives small ligand field splitting, while carbon monoxide gives a strong field and a large Δ. The energy difference Δ over this range of ligands increases by a factor of about two. It must be noted that this series must be used as a simple and useful rule and not taken as universally accepted, as it has ... boom insectosWebWeak field ligands: Weak field ligands are those ligands that can not pair the valence electrons of a metal ion. Normally, Aqua (H2O) is considered a weak field ligand. But in the case of the metal ion having an oxidation state +3 or higher than +3 and transition metals of 4d and 5d series, H2O acts as a strong ligand.
