The transition metal ion, Fe(III), can form octahedral or tetrahedral complexes depending on the ligand it binds to. (a) (i) [Fe(CN)6]3- is a strong field octahedral complex of Fe(III). Draw a labelled orbital energy level diagram that shows both the splitting of the d-orbitals and their electron occupancy in [Fe(CN)6]. (3 marks) (ii) Fe(III) can also form tetrahedral complexes, most of which are weak field. Draw a labelled orbital energy level diagram that shows both the splitting of the d-orbitals...

Make two d-orbital diagrams for each of the transition metal compounds, that show the low and high-spin states. Assume the compounds have an octahedral geometry. Determine the value of the spin-only magnetic moment for each of these configurations. Explanation of determining the value of spin-only magnetic moment would help.

Electron configurations of transition metal ions Zinc is an essential mineral of great biological and health importance. In fact, it is the second most abundant transition metal after iron in our body. Most exists as Zn2+ ion in active site of enzymes, and they (more than 300) perform an array of functions. a. What is the electronic configuration of the Zn atom. b. Here comes the irritating part in chemistry. Although the 3d orbitals are placed higher in energy than...

SYNTHESIS OF TRANSITION METAL COORDINATION COM 3. Ethylenediamine ("en" in short-hand notation) has two amine groups, one at each end of a two-carbon chain, NH,CH,CH,NH. Each nitrogen in NH,CH,CH_NH, has a lone pair that coordinates to the metal. Thus, one NH CH CH NH, ligand, takes up two coordina- tion sites. a) Draw and label the structures of the cis and trans isomers of Co(en),C1,CI. b) What is the coordination number for (Coſen),C1,CI? c) Determine the oxidation state of the...
