Coordination polyhedra, bonding, role

A parameter, which is of special importance for the description of M(OR)n in addition to the coordination polyhedron of the central atom and the M-O bond lengths, is the M-O-C bond angle. Bradley [198] was the first to emphasize the role of unshared electron pairs at the oxygen atoms that can be involved into interaction with the vacant t/-orbitals of the transition metal. Thus in the molecules containing maingroup metals such as Bi, Sn, Ge, Te, and Al. the values of these angles usually do not exceed 120 to 130°, while in those of... [Pg.40]

A partial explanation for this surprising difference is provided by a combination of an analysis of the role of magnetic site coordination polyhedron in determining the electronic structure and application of the Spin Dimer Model.The octahedron about Os in Li50s06 is subject to a much stronger psuedo-tetragonal compression, 4 Os - O bonds at 1.908 A... [Pg.56]
