Co-crystals formed by coordination complex coformers and chiral organic coformers are difficult to obtain. We found that chiral spiroborate anions (S,S)- and (R,R)-bis(1,1′-binaphthyl-2,2′-diolato)boron may undergoinsitualcoholysis reactions at room temperature. The generated tetramethoxyborate anions act as terminal ligands to assemble Zn2Dy2Schiff base tetranuclear complexes, while the other alcoholysis products (S)- and (R)-1,1′-binaphthalene-2,2′-diol ((S)-binol and (R)-binol, respectively) are coformers that co-crystallize with the Zn2Dy2tetranuclear compound to form chiral co-crystals with magnetic relaxation behavior, namely, {Zn2Dy2(OH)2(LSchiff)2[B(OCH3)4]2Cl2}·2((S)- or (R)-binol)·2H2O·MeOH (H2LSchiff= 2-((Z)-(3-((Z)-2-hydroxy-3-methoxybenzylideneamino)propylimino)methyl)-6-methoxyphenol,(S)-1: with (S)-binol, and(R)-1: with (R)-binol). They represent the first chiral single-molecule magnet (SMM) eutectics through the co-crystallization of SMMs and chiral organic coformers.
