- Amines, NR3, are usually only weakly coordinating toward low valent metals. why is this so?Do you think that NF3would be abetter ligand for these metals? Discuss the factors involved.(a) A compound with formula RuCl3 . 5 H2O is dissolved inwater, forming a solution that is approximately the samecolor as the solid. Immediately after forming the solution,the addition of excess AgNO3(aq) forms 2 mol of solid AgClper mole of complex. Write the formula for the compound,showing which ligands are likely to be present in the coordinationsphere. (b) After a solution of RuCl3 . 5 H2O hasstood for about a year, addition of AgNO3(aq) precipitates 3mol of AgCl per mole of complex. What has happened inthe ensuing time?The mineral magnetite has the formula Fe3O4 and has an inverse spinel structure. In the unit cell, there are two Fe ions in octahedral sites and one Fe ion in a tetrahedral site. (i) Are the Fe ions in magnetite low-spin or high-spin? Explain your reasoning. (ii) Draw d-orbital splitting diagrams for Fe(III) in tetrahedral and octahedral ligand fields and hence deduce the CFSE in each case. (iii) On the basis of your answer to part (ii) above, do you expect Fe(III) to have a preference for tetrahedral or octahedral sites? Explain your answer. (iv) Draw d-orbital splitting diagrams for Fe(II) in tetrahedral and octahedral ligand fields and hence deduce the CFSE in each case. (v) Assuming that Δt ~ 4/9 Δo and using your answer to part (iv) above, deduce the CFSE of Fe(II) in a tetrahedral field in terms of Δo. Hence decide whether the tetrahedral site is occupied by Fe(II) or Fe(III), explaining your reasoning.
- Generally speaking, for a given metal and ligand, the stability of a coordination compound is greater for the metal in the +3 rather than in the +2 oxidation state (for metals that form stable +3 ions in the first place). Suggest an explanation, keeping in mind the Lewis acid–base natureof the metal–ligand bond.Dimethyldithiocarbamate (abbreviated as dmdtc) is an anionic bidentate ligand with a chemical formula (S2CNMe2)- - where Me stands for methyl group (-CH3). In the photo above, this ligand coordinates to a metal through its 2 sulfur atoms (where M represents a metal). When three dmdtc ligands bind to a ferric ion (Fe3+), a stable coordination complex called ferbam is formed.

- Write a complete and balanced redox equation for the synthesis of the coordinationcompound. Use iron(II) oxalate (the yellow/orange solid) as a reactant. In other words,complete the following reaction: FeC2O4(s) + H2O2(aq) + ??? → product(s) Assume that the net reaction occurs in an acidic solution: this will make balancing theequation easier. Use the formula of the iron (III) oxalate compound that you found in theliterature to balance the equation ([Fe(C2O4)3]). You must write out the individual half-reactions.Draw the appropriate completely Orgel Diagram and use it to assign elctronic transition/s to any of these bands , confirming the colour of the complexIs there a way to tell which ligands are strong-field and which are weak-field, or is that just something I need to memorize?
