Many trace metal ions exist in the blood complexed with amino acids or small peptides. The anion of the amino acid glycine (gly), H,NCH,C-O can act as a bidentate ligand, coordinating to the metal through nitrogen and oxygen atoms. How many isomers are possible for (a) [Zn(gly)2] (tetrahedral), (b) [Pt(gly)2] (square planar), (c) [Co(gly)3] (octahedral)? Sketch all pos- sible isomers. Use the symbol to represent the ligand.

Transition metal complexes are highly likely to be colored because of a) the size of the energy gap within the d orbitals and the number of electrons. In ruby, the red color of ruby is attributed to a small amount of Cr³* substituting into Al2O3 which is made up of shared AIO, octahedra. Provide a hypothesis for the origin of the red color observed in ruby. Red pigments tend to be rare. If you had to design a new material that b) had an approximate bandgap that would absorb green, what ideas do you need to employ to find a new semiconductor that does not contain Cd, Hg or Pb as one of the components (see last lecture for ideas).
