Development of chiral N,N-ditopic metalloligands based on a Cinchona alkaloids' backbone for constructing homochiral coordination polymers

The bimetallic chiral bipyridyl-type metalloligands based on aluminium derivatives of cinchonine, R(2)Al(μ-CN)](2) (R = Me or Et), in combination with the corresponding ZnR(2) compound as nodes were used for the generation of novel homochiral heterometallic coordination polymers of either zig-zag or helical topology, depending on the character of the R substituent.
