摘要：

The title compound, [Co2Na2{mu(2)-N(SiMe3)(2)}(4)](mu(4)-O), (I), represents a new entry in the class of inverse crown ethers. In the molecule, each Co atom is formally in the oxidation state +II. The structure contains one half of a unique molecule per asymmetric unit with the central mu(4)-oxido ligand residing on an inversion center, leading to a planar coordination to the Na and Co atoms. In the crystal, bulky trimethylsilyl substituents prevent additional interactions with cobalt. However, weak intermolecular Na center dot center dot center dot H3C-Si interactions form an infinite chain along [010]. The structure is isotypic with its Mg, Mn and Zn analogues.
