摘要：
A flexible bis(pyridylurea) ligand, 1,1'-[oxybis(2,1-phenylene)] bis(3-pyridin-3-ylurea) (L), has been synthesized and characterized. The interaction of L with ZnCl2 and CdCl2 has been investigated. In the structure of {[ZnLCl2]center dot 2DMF}(n) (1), the flexible ligands bridge the Zn-II centers to form 1D helical chains with a pitch of 9.743 angstrom. The P and M helical chains are arranged equally, and the whole complex 1 is racemic. In the structure of [CdLCl2(DMF)](n) (2), the flexible ligands bridge Cd-II centers to form one-dimensional P and M helical chain structures in a similar manner. Then the chlorine atoms act as bridges in bidentate modes linking the P helical chain with M helical chain to form a 1D looped chain coordination polymer. (C) 2018 Elsevier B.V. All rights reserved.
