2. (3 points) In lab, you will form complexes using different ligands. Use your lab manual to identify and draw the structural formula (lewis formula) for the following: a. A charged monodentate ligand (answer cannot be a halide ion) b. A polydentate ligand c. The CO ligand, not used in the laboratory. Is it likely CO can form a coordinate covalent bond from more than one atom? Explain. NC CN Ni Geometry of Coordination Compounds A compounds geometry (i.e., how...
The number of bonds between a metal ion and its ligands is can the complex ion. If four monodentate ligands na metal ion and its ligands is called the coordination number of coordination number in the complex ion is four. SIX four monodentate ligands or two bidentate ligands bond to a metal ion, the ethylenediamine molecules, or two diethylenetriamine molecules bonded oer in the complex ion is four. Six water molecules, or six cyanide ions, or three torm a complex...
For each of the following metal complexes, specify the number of ligands, the coordination number of the metal, the oxidation number of the metal, the geometry of the complex and draw the structure. Transition metal complexes with four ligands usually form tetrahedral structures unless the metal has a d8 configuration, in which case it can form either tetrahedral or square planar structures.

Exercise 1: 1. What kind(s) of interaction between the ligand and the metal ion is(are) considered in the crystal field approach? 2. Give and justify the degeneracy lifting for a tetrahedral complex. Would it be the same for an octahedral complex? 3. Let us consider hexaaquacopper(II) ion. Justify the elongation of two opposite Cu-O bonds (along z for example) compared to the other four Cu-O bonds using...
