Wh. Lam et Zy. Lin, Structural preference in complexes containing both double-face and single-face pi-acceptor ligands, J ORGMET CH, 635(1-2), 2001, pp. 84-91
The development of the Dewar-Chatt-Duncanson model has a great impact on co
ordination/organometallic chemistry in terms of understanding the structure
and bonding in metal complexes containing pi -accepting ligands. The major
ity of pi -acceptor ligands can be categorized into two types: double-face
and single-face pi -accepting ligands. Metal complexes containing both sing
le-face and double-face pi -accepting ligands show unique structural prefer
ences. In this paper, the structural consequence for these complexes will b
e discussed with the aid of density functional theory calculations. Example
s include eta (1)-alkenyl, eta (2)-silane, eta (2)-alkene and boryl octahed
ral complexes. (C) 2001 Elsevier Science B.V. All rights reserved.
