The reaction of the flexible bis(imidazole) ligand 1,4-bis(imidazol-1-yl)butane (bimb) with corresponding Cd(II) salts (NCS − , dicyanamide (dca), N3-, ClO4-) yields four new coordination polymers, from 1D to 3D networks, namely [Cd(bimb) 2 (NCS) 2 ] n (1), [Cd(bimb)(dca) 2 ] n (2), [Cd(bimb)(N 3 ) 2 ] n (3) and {[Cd(bimb) 3 ](ClO 4 ) 2 } n (4). In 1, each Cd(II) atom links two Cd(II) atoms by double bimb ligands and extends to form an one-dimensional chain structure containing the Cd 2 (bimb) 2 22-membered metallocycle. In 2, double μ 1,5 -dca bridges connect the Cd(II) atoms to form the zigzag [Cd(dca) 2 ] n chains and extend through bimb long bridges in four different directions alternatively to construct a novel three-dimensional network. In 3, double end-to-end (EE) and double end-on (EO) azide short bridges alternatively link Cd(II) atoms to form the [Cd(N 3 ) 2 ] n chains containing both eight- and four-membered metallocycles which further extend via bimb long bridges in four different directions alternatively to result a three-dimensional network. Compound 4 comprises two equivalent, mutually interpenetrating three-dimensional networks.
