Chirality is an essential element in life and indispensable for many biological processes,the utilization of chirality in metal-organic frameworks(MOFs)is an interesting phenomenon,not merely due to their aesthetic structural beauty but mainly due to their relevance in chiral separation,enantioselective sensing,asymmetric catalysis,luminescence,magnetism,and nonlinear optical applications.In this paper,a novel chiral metal-organic framework based on copper(Ⅱ)and mixed ligands [Cu2(bzgluO)2(bpe)2]n·5nH2O(1)(H2bzgluO = N-benzoyl-L-glutamic acid,bpe = 1,2-bis(4-pyridyl)ethane)has been synthesized and structurally characterized by single-crystal X-ray diffraction.The X-ray structural determination indicates that complex 1 crystallize in the monoclinic space group P2(1),features a chiral 3D porous framework which consists of 1D open channels possessing approximate dimensionalities of 10.05(A)along the c axis.Interestingly,the host framework encapsulates unique octameric water clusters.
