RESUMEN
Unexpected panelling by µ6-CO3(2-) anions has been observed to support the formation of a new and unusual Co15 cluster. The arrangement is further stabilised by bis-phenolate ligands which assemble in a manner akin to tetrahomodioxacalix[4]arene. The reaction proceeds in very low yield as µ6-CO3(2-) anions are formed in situ, but targeted synthesis by addition of carbonate improves synthetic yield and highlights the pivotal role of this anion in the overall assembly process.

RESUMEN
The initial use of oxacalix[3]arene in manganese chemistry affords an unusual [Mn(10)] supertetrahedron with an even more unusual oxidation state distribution.
