1 (i) Discuss how the nature of the ligand, position of the metal in the d-block elements and metal oxidation state influence the magnitude of the d orbital splitting in metal complexes, (as applied in crystal field theory). Outline the principal differences between the 1st row and 2nd/3rd row transition metal complexes.
(ii) Describe with relevant examples and diagrams the several types of isomerism which are commonly encountered in transition metal complexes.

1 . Describe the chemistry of the group 14 elements with reference to (i) decreasing catenation, (ii) increased metallic behaviour on descending the group and (iii) the relative stability of the +2 and +4 oxidation states. 2. Discuss with relevant examples how the stability of the +2 oxidation state varies across the 1st row transition metals. Describe with relevant examples the general types of ligands that can stabilise higher oxidation states in metal complexes. 3. Discuss in detail the spectroscopic...
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...
