Abstract

The treatment of [Co(D- or L-ebp)] with CdX2 (X = Br, I) gave a cyclic CoIII3CdII3 complex with a 12-membered metalloring, [Cd3X3{Co(D- or L-ebp)}3] (D3- or L3-1X). The use of a 1 : 1 mixture of [Co(D-ebp)] and [Co(L-ebp)], instead of [Co(D- or L-ebp)], led to the creation of a cyclic CoIII6CdII6 complex with a 24-membered metalloring, [Cd6X6(H2O)6{Co(D-ebp)}3{Co(L-ebp)}3] (D3L3-2X). Compounds D3L3-2X were also produced when D3-1X and L3-1X were mixed in water in a 1 : 1 ratio, illustrating the conversion of a pair of homochiral metallorings into a double-sized heterochiral metalloring.
