The research about crystal structure and chirality of nucleotides coordination complexes and supramolecular assembly is significant.Different kinds of chirality including chiral coordination environment of metal center, supramolecular helix as well as Extended Axial Chirality (EAC) can coexist in these nucleotides complexes as well as supramolecular assembly which are nicely studied based on single crystal X-ray diffraction and circular dichroism in solid-state (Fig.1).
