WebThe tetrahedral cluster is a distorted cubane structure with Li and CH 2 R groups at alternating vertices. An equivalent description describes the tetramer as a Li 4 tetrahedron interpenetrated with a tetrahedron [CH 2 R] 4. Bonding within the cluster is related to that used to describe diborane, but more complex since eight atoms are involved. WebPhotoelectron spectroscopy and density-functional theory are combined to investigate the electronic and structural properties of a series of B-Au alloy clusters: B6Aun(-) and B6Aun (n = 1-3). Rich spectral features are observed for each species, and vibrational structures are resolved for numerous detachment transitions of B6Au(-) and B6Au2(-).
