Project description:The crystal structure of a two-dimensional metal–organic compound constructed from 4,4′-bis[(1H-imidazol-1-yl)methyl]-1,1′-biphenyl (BIMB) and nickel ions is described. Each BIMB ligand adopts a linear linker to connect Ni2+ ions, forming a layer with an sql network.

Each BIMB ligand adopts a linear linker to connect Ni2+ ions, forming a two-dimensional layer with an sql network. In the crystal, neighboring layers repeat in an ABAB stacking mode, and weak intermolecular C—H⋯Cl hydrogen bonds between alternate layers lead to a three-dimensional, twofold interpenetrated, supramolecular framework with a pcu topology net.
