• 1 is an uncommon self-penetrating net assembled from intertwined homo-axis helices.
• Complex 1 can be simplified to a unique trinodal 4-connected network.
• Complex 1 exhibits an unprecedented (5.64.8)(52.63.8)(52.62.7.8) topology.
Hydrothermal reaction of the flexible V-shaped ligand 3,3′,4,4′-diphenylsulfone tetracarboxylic acid (H4dpstc) with nickel salt in the presence of long-chain N-donor ligand affords a fascinating entangled network, [Ni2(dpstc)(bim)2(H2O)]·2H2O (1) (bim = 1,4-bis(imidazol-1-yl)butane). Complex 1 represents an unusual 3D self-penetrating entangled framework, which is based on novel 2D helical layers. More interestingly, the 2D helical layers are constructed by the intertwined homo-axis covalent helices running along the same crystallographic 21 axis in the b direction. Furthermore, the magnetic properties of complex 1 have been studied by measuring its magnetic susceptibility in the temperature range 2–300 K.
