Question

Problem 3 For each of the molecules shown below (some of which are hypothetical): I. Provide an electron count, mentioning whether there is any ambiguity and assigning what you think is the best count (this is not totally subjective, so be careful). For some ligands, electron counting can change depending on the ligand conformation (e.g., linear versus bent NO), If there is any ambiguity as to the structure and thus the count, sketch the one you think leads to the most stable structure and count. II. Assign a formal oxidation state to each metal. III. Assign a valence number to each metal IV. If there is more than one metal, state whether your valence electron count suggests the presence of direct M-M bonding, and if so the bond order. V. Mention whether you think the molecule might be electronically stable. a) f) h) i) ) (0) 2
