(50 pts) Two Fe complexes, [Fe(bpy)2(CN)2] and [Fe(bpy)2(BCF)2], are shown here: iv a. (10 pts) Dete:mine the electron configuration and the valence electron count of Fe in both compounds. Are they diamagnetic or paramagnetic? b. (10pts) The CNB bond angle in [Fe(bpy)2(BCF)2] is about 171.8. Provide a reason why the CNB bond deviates from the expected linear arrangement. c. (20 pts )[Fe(oppy)2(CN)2] can be considered of a C2 point group; the character table of it is given below. Considering the CN stretching bands only and using group theory, perform a partial vibrational analysis and determine how many IR bands should be observed for the CN stretching. d. (10 pts) In thie IR spectrum of [Fe(bpy)2(CN)2],CN stretching modes are observed at 2070 and 2077cm1, while in [Fe(bpy)2(BCF)2], two bands at 2166 and 2181cmi are observed.
