Guest-Induced Helical Metallacyclic Chains in a Porous Coordination Solid Constructed from a Flexible Ester-Containing Ligand
dataset
posted on 2007-02-07, 00:00 authored by Kexuan Huang, Zhengjiang Xu, Yizhi Li, Hegen ZhengA porous metal−organic framework [Co(SCN)2(EDPC)2(H2O)3]n (1; EDPC = 1,2-ethanediyl di-3-pyridinecarboxylate) has
been synthesized and structurally characterized. Immersing the crystals of 1 in THF solution led to the dynamic framework of 1 undergoing
a crystal-to-crystal guest-exchange process to afford the helical metallacyclic polymer [Co(SCN)2(EDPC)2(THF)]n [1⊃THF]. The guest
THF molecules were accommodated in the cavities of the metallacyclic chains and showed the handness of the helical chains by their
oxygen atoms as probes.
