Synthesis and characterization of a novel chiral solid, {Co(H₂N(CH₂)₂NH₂)₃}[V₃O₉] · H₂O (1), containing chiral vanadium oxide chains constructed from corner sharing tetrahedral {VO₄} units and propagated by a twofold screw axis are described. The resulting [{V₃O₉}³⁻]_n chains host dissymmetric {Co(H₂N(CH₂)₂NH₂)₃}³⁺ species, which functions as an optically active template. The synthesis of 1 demonstrates the potential application of an optically active complex compound of D₃ symmetry as a chiral template in the synthesis of chiral chemical systems with extended structures.
