Are structures for all of the possible isomers of six coordinate compounds [Co(NH3)4Cl2] and[Co(NH3)3Cl3].

1. The Cp2Rh2[u-(CF3C=CCF3)](CO)(CNR) complex has a Rh-Rh bond distance of 2.67 Å, strongly indicating a covalent bond between the rhodium atoms. How would you electron count this complex to accommodate a Rh-Rh covalent bond? Clearly show the electron counting.

Predict the products of the following reaction.  Co(s) + xsF2(g)---->

5. Combinations of Co(III), NH3, NO2 and K* can result in the formation of a series of seven coordination compounds (with 6-coordinate complexes), one of which is [Co(NH;)6](NO2)3. (a) Write the formulas for the other six members of the series. (b) Name each of the seven compounds. (c) Which, if any, of the compounds should form cis/trans geometric isomers? (d) Which, if any, of the compounds should form merlfac geometric isomers? Which, if any, of the compounds would be optically active (i.e., form non- superimposable mirror images)?
