Abstract
This Viewpoint describes major advances pertaining to perfunctionalized boron clusters in synthesis and their respective applications. The first portion of this work highlights key synthetic methods, allowing one to access a wide range of polyhedral boranes (B4 and B6-B12 cluster cores) that contain exhaustively functionalized vertices. The second portion of this Viewpoint showcases the historical developments in using these molecules for applications ranging from materials science to medicine. Last, we suggest potential new directions for these clusters as they apply to both synthetic methods and applications.

Abstract
The normal mode frequencies and corresponding vibrational assignments of B4Cl4 are examined theoretically using the Gaussian 98 set of quantum chemistry codes. All normal modes were successfully assigned to one of three types of motion predicted by a group theoretical analysis (B-B stretch, B-Cl stretch, B-Cl bend) utilizing the Td symmetry of the molecule. The vibrational modes of the naturally isotopically substituted (1-(10)B, 2-(10)B, 3-(10)B and 4-(10)B) forms of B4Cl4 were also calculated and compared against experimental data. A complex pattern of frequency shifts and splittings is revealed.
