The racemic compound and enantiomer (Δ-Δ and/or Λ-Λ) of the di-μ-hydroxo-bis[bis((1S,2S)-1,2-trans-cyclohexanediamine)-chromium(III)] and/or di-μ-hydroxo-bis[bis((1R,2R)-1,2-trans-cyclohexanediamine)chromium(III)] complexes (Λ,Λ-[Cr 2 (OH) 2 (S,S-chxn)]Br 4 and/or Δ,Δ-[Cr 2 (OH) 2 (R,R-chxn)]Br 4 ), were found to be formed in the solid state together with the meso compound (Λ,Δ-[(S,S-chxn) 2 Cr(OH) 2 Cr(R,R-chxn) 2 ]Br 4 ) by dehydrating the hydroxoaqua complexes, Λ-cis-[Cr(OH)(S,S-chxn) 2 (H 2 O)] Δ-cis-[Cr(OH)(R,R-chxn) 2 (H 2 O)]Br 4 3H 2 O and Λ-cis-[Cr(OH)(S,S-chxn) 2 (H 2 O)]Br 2 1.5H 2 O, assumed to consist of the homochiral or heterochiral aggregates with hydrogen bridges between the hydroxo and aqua ligands.
