Abstract: | Crystallization of Cd(S‐thpc12)](ClO4)2·H2O {S‐thpc12 is 1,4,7,10‐tetrakis(S)‐2‐hydroxypropyl]‐1,4,7,10‐tetraazacyclo‐dodecane} in the presence of sodium p‐nitrophenolate forms the title complex, Cd(C20H44N4O4)](C6H4NO3)(ClO4)·H2O, in which p‐nitrophenolate and water separately hydrogen bond to a different pair of cis‐related pendant hydroxyl groups which, together with the four N atoms, are themselves bound to CdII in an approximately square antiprismatic arrangement. The diastereoselectivity of the complex‐forming process is apparent from the fact that both different disymmetric cations in the asymmetric unit have the same Δ helicity. |
