Comparative X-ray structural studies on [ Fe(/X3-CO)Cp 4] [Z = 0 (161) and 1 (162)) showed that the fully bonded tetrahedron of metal atoms (Fe—Fe = 252 pm) undergoes only minor distortions on oxidation, with a slight shortening of the average iron-iron distance to 248 pm. Electron removal from an orbital largely nonbonding with respect to the tetrametal framework was deduced (161).

SiC has fascinated material scientists not only for its extreme mechanical, thermal and electronic properties but also because of its unusual structural properties. The basic unit of SiC consists of a covalently bonded tetrahedron of Si (or C) atoms with a C (or Si) at the centre. The identical polar layers of Si4C (or C4Si) are continuously stacked and the permutation of stacking sequences allows an endless number of different one-dimensional orderings (polytypes) without variation in stoichiometry.

If VECa < 8 Polyanionic valence compound with /VA > 0 and C C = 0. The value of / A can be calculated using (7). Tetrahedra are linked by covalent A - A bonds (tetrahedron variant (II)) and, depending on the composition, also by sharing anions (tetrahedron variant (I)). The parameter of interest is the average number of A - A bonds per tetrahedron. Since there are n anions for every m central atoms, its value is given by... 

This equation is appiicable in the case that each anion is either unshared or shared with oniy one other tetrahedron. The x parameter refers to the electrons which remain with the central atom In the case of polycationic valence compounds. It expresses the ratio of the number of vaience eiectrons used for C - C bonds between the centrai atoms to the totai number of eiectrons which rest with the central atom to be used for C - C bonds (tetrahedron variant (III)) and lone electron pairs (tetrahedron variant (iV)). When X = 1 the eiectrons are used oniy for C - C bonds, and when x = 0 oniy for ione pairs. We shaii find out beiow that for the most common cases one does not need to consider the x vaiue.
