Templated synthesis of a chiral solid: Synthesis and characterization of {Co(H2N(CH2)2NH2)3}[V3O9] · H2O, containing a new type of chiral vanadium oxide chain

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.
