Notes:
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.
