3) A shape controlled Ag nanoparticle synthesis uses ligands that have selective affinities of different crystallographic surfaces of Ag. When the ligand binds preferentially to a crystal plane, growth slows in the direction normal to that plane, while Ag addition to surfaces growing along other directions proceeds quickly. These relative growth kinetics result in solids with facets of the plane preferentially bound by the ligand. What shape nanoparticles do you expect for ligand that selectively bind to the following surfaces of Ag, which has an FCC crystal structure: a) (111) b) (001) c) a mix of (111) and (001)

n 1982, F. A. Cotton and D. J. Darensbourg published a paper in Inorganic Chemistry (v21, pp. 2661-2666) describing the kinetics of isomerization of cis/trans-Mo(CO)4(PR): complexes. One of the pure isomers (A) gave rise to 4 CO stretching bands. Upon heating, the other isomer (B) began to form and a single new CO stretching band appeared. A: 4 CO stretching bands (2019, 1922, 1905, and 1899 cm) B: I CO stretching band (1895 cm) y R₂P PR3 OC-Mo R active modes for cis: CO OC CO cis C₂v ос R₂P Mo OC PR₂ trans Dah For both isomers shown above (cis C and trans Das), determine how the CO bond vectors transform under the symmetry operations of their respective point groups to generate the reducible representations for CO bond stretching.

Also, all C-M-C bond angles for nearest neighbor cyanide ligands are 90°. b.

Determine the symmetry point groups of the mer- and fac- isomers of the complex [Re(CO)3(NCMe)3] and deduce the irreducible symmetry representations generated by the three stretching vibrations of the C triple bond to N ligands in each of the isomers. [Regard NCMe as a linear ligand.] Also for each isomer discussed, state with reasoning which vibrations are IR active, and which are Raman active and how many bands will be observable in IR and Raman spectra. How can you distinguish the two isomers using their vibrational spectra?
