摘　　要：By varying the spacer angles of phenylenediacetic acid, two novel Zn（II） coordination polymers based on semirigid N-heterocyclic ligand 1,4-bis（2-ethylbenzimidazol-1-ylmethyl） benzene, [Zn（beb）0.5（m-phda）]n（1） and {[Zn（beb）（p-phda）]·2H2O}n（2）, were synthesized and fully structurally characterized. Polymer 1 exhibits a 2D grid-layer with a 44 topology. Polymer 2 shows a 2D layer with rare meso-helix. In addition, the thermal stability and photoluminescence properties of polymers 1 and 2 have also been investigated.By varying the spacer angles of phenylenediacetic acid, two novel Zn（II） coordination polymers based on semirigid N-heterocyclic ligand 1,4-bis（2-ethylbenzimidazol-1-ylmethyl） benzene, [Zn（beb）0.5（m-phda）]n（1） and {[Zn（beb）（p-phda）]·2H2O}n（2）, were synthesized and fully structurally characterized.
