Abstract: Crystallization of [Cd(S-thpc12)](ClO4)2·H2O {S-thpc12 is 1,4,7,10-tetrakis­[(S)-2-hydroxy­propyl]-1,4,7,10-tetra­aza­cyclo­do­decane} in the presence of two equivalents of sodium picrate monohydrate (sodium 2,4,6-tri­nitro­phenolate monohydrate) diastereoselectively produces a neutral receptor complex, viz. the title compound, Λ-[Cd(C20H44N4O4)](C6H2N3O7)2·CH3CN. In this complex, two picrate anions hydrogen bond, via their phenolate moieties, to the pendant hydroxyl groups of the receptor which, together with the four N atoms, themselves bond to CdII in an approximately cubic arrangement. One picrate anion hydrogen bonds to all four hydroxyl groups, one of which also acts as the sole hydrogen-bond donor to the second picrate anion.
