✦ Synopsis
Two new nickel (II) supramolecular complexes, [Ni(HCPIDA)(H 2 O) 3 ] (1) and [Ni 2 (HCPIDA)
acid, bpyZ4,4 0 -bipyridine) were synthesized through hydrothermal method. These supramolecular complexes have been structurally characterized by X-ray single crystal diffraction. The structure of 1 exhibits a new three-dimensional supramolecular framework with one-dimensional channels, formed by hydrogen bonding interactions. The structure of 2 shows a new twodimensional joint-ladder like architecture constructed by hydrogen bonding and p-p staking interactions. The compounds 1 and 2 contain the zigzag-shape and ladder-shape supramolecular chains, respectively, which further extend into the three-dimensional and twodimensional supramolecular network, respectively.
