Two new Ni(II) coordination polymers (CPs), [Ni(L1)(IPA)](n) (1) and [Ni(L2)(IPA)center dot H2O](n) (2) (L1 = 1,6-bis (benzimidazol-1-yl)hexane, L2 = 1,6-bis(5,6-dimethylbenzimidazol-1-yl)hexane, H(2)IPA = isophthalic acid) were synthesized by hydrothermal and sonochemical process. X-ray crystal structure analysis revealed that 1 possesses a 4-connected 3D architecture with a 6(5.)8 CdSO4 topology, while 2 exhibits a 2D layer, which can be classified as a honeycomb 6(3)-hcb network. The results indicate that Ni(II) mixed CPs structurally modulated by the flexible bis(benzimidazole)-involved co-ligands. The role of ultrasound irradiation power, reaction time and reaction temperature on the size and morphology of the nano-sized 1 and 2 were investigated in detail. Further, fluorescence and photocatalytic activities of nano-sized CPs for degradation of methylene blue (MB) are presented. (C) 2018 Elsevier Ltd. All rights reserved.
