single-crystal X-ray diffraction. The results indicate that in compound 1, the H3L1 ligands adopt bis-monodentate coordination mode to connect the two kinds of 1D Ni-4,4′-bipy-Ni chains, giving a 3D network with rare (42·63·8)2(6·84·10) topological structure. In compound 2, H3L2 ligand acts as the terminal mode while the 4,4′-bipy ligands bridge the Ni(II) ions to generate infinite Ni-4,4′-bipy-Ni zig-zag chains
