Determine the point groups:

a. Cu(acacCN)₂ and tpt in Problem 9.28. (Assume delocalization of electrons in the part of the acacCN ligands and in the aromatic rings of tpt.)

b. A molecular cartwheel (note orientation of rings). (See H. P. Dijkstra, P. Steenwinkel, D. M. Grove, M. Lutz, A. L. Spek, G. van Koten, Angew. Chem., Int. Ed ., 1999 , 38 , 2186.)
