Crystal structures octanuclear complexes

Another example of a complicated polynuclear complex is an octanuclear basic benzoate containing four vanadium(IU) and four zinc(II) atoms [VZn0(02CPh)3(THF)]4-2THF.27D The crystal structure shows that the distances between these four vanadium atoms are just below 3 A and therefore some V—V bonding may occur. 

FIGURE 78 Syntheses of hexanuclear and octanuclear samarium cluster complexes and their reaction with dinitrogen to afford tetranuclear cluster species containing a N2 ligand derived from dinitrogen reduction (top). The crystal structures of the hexanuclear (bottom left) and octanuclear (bottom right) clusters are shown (redrawn after Ganesan et al 2001). 

Several crystal structures of cadmium-thiolate complexes with nuclearity higher than 4 can be found in the literature. For example, the octanuclear molecule [Cdg(SPhF-3)i4(DMF)6(N03)](N03) [97] (Figure 27) consists of a cubic cluster...
