Structural Analysis of Cubane-Type Iron Clusters.

ABSTRACT: The generalized cluster type [M₄(μ₃-Q)₄L _n ] ^x contains the cubane-type [M₄Q₄] ^z core unit that can approach, but typically deviates from, perfect T_d symmetry. The geometric properties of this structure have been analyzed with reference to T_d symmetry by a new protocol. Using coordinates of M and Q atoms, expressions have been derived for interatomic separations, bond angles, and volumes of tetrahedral core units (M₄, Q₄) and the total [M₄Q₄] core (as a tetracapped M₄ tetrahedron). Values for structural parameters have been calculated from observed average values for a given cluster type. Comp
