Enantiomerically pure polytungstates: Chirality transfer through zirconium coordination centers to nanosized inorganic clusters

(Figure Presented) Small but influential: Chirality transfer from a small chiral organic unit (D- or L-tartrate) to a very large metal-oxide framework is demonstrated by the enantiomerically pure, nonracemizing polytungstates D- or L-1 (see picture, the central part is shown in polyhedral form; purple Zr, gray W, blue P, black C, red O). The tartrate unit determines the absolute configuration of the inorganic moiety, offering a new method to control the chirality of polyoxoanions.
