A novel chiral interpenetrating 3-D coordination polymer constructed by different numbers of left- and right‐handed helical chains

A novel coordination polymer [Co(bpbc)(H2O)2]n (1) was synthesized by hydrothermal reaction of Co(OAc)2·2H2O and 2,2′-bipyridine-4,4′-dicarboxylate acid (H2bpbc). X-ray single diffraction studies reveal that compound 1 exhibits chiral two-fold interpenetrating 3-D network, which contains different numbers of left- and right-handed helical chains. The magnetic property is also investigated.
