Cluster expansion reactions of group 6 metallaboranes. Syntheses, crystal structures, and spectroscopic characterizations of (Cp*Cr)(2)B5H9, (Cp*Cr)(2)B4H8Fe(CO)(3), (Cp*Cr)(2)B4H7Co(CO)(3), and(Cp*Mo)(2)B5H9Fe(CO)(3)

Abstract:

The targeted high-yield syntheses of a number of new clusters by the controlled addition of BH, Fe(CO)3, or Co(CO)3 fragments to dinuclear group 6 metallaboranes are reported. The reaction of the chromaborane, (Cp*Cr)2B4H8 (1), Cp* = η5-C5Me5, with BHCl2·SMe2 results in a cluster expansion reaction giving the green-brown diamagnetic species (Cp*Cr)2B5H9 (2) in 43% yield. The six skeletal electron pair (sep) cluster has a structure based on a trigonal bipyramidal Cr2B3 unit with adjacent Cr2B ...
