Hexanuclear cobalt cages

A planar hexanuclear cobalt cage, [Co6 (PhSi02)6 2CKsolvent)6] , which has the same metal core as the manganese(II) cage 28, has been reported (87). The experimental details are so limited that it is difficult to identify the molecules attached in the axial positions of the six cobalt centers. 

The first hexanuclear cobalt(II) cage reported was [Co6(02CNEt2)i2]/ which has a similar structure to Mn° and Fe complexes of the same ligand (see Sections 7.3.2.3 and 7.3.2.4 above). 

Hexanuclear cages with carbamate ligands have been reported for manganese, iron, and cobalt. The manganese cage, [Mn6(02CNEt2)6], is made by addition of [Mn(Cp)2] to a solution of NHEt2 in toluene.
