Eight 2D and 3D coordination polymers, [Mn(NBPDC)(1,4-bimb)]n (1), [Zn(NBPDC)(1,4-bimb)]n (2), [Cd(NBPDC)(1,4-bimb)]n (3), [Mn2(NBPDC)2(1,3-bimb)(H2O)]n (4), {Zn(NBPDC)(1,3-bimb)}n (5), [Cd2(NBPDC) 2(1,3-bimb)2(H2O)]n (6), [Mn(NBPDC)(4,4′-bimbp)]n (7), and [Cd2(NBPDC) 2(4,4′-bimbp)2]n (8), (NBPDC = 2,2′-dinitro-4,4′-biphenyldicarboxyl acid, 1,4-bimb = 1,4-bis(imidazol-1-ylmethyl) benzene, 1,3-bimb = 1,3-bis(imidazol-1-ylmethyl) benzene, and 4,4′-bimbp = 4,4′-(bis(imidazol-l-ylmethylene)) biphenyl), have been prepared and structurally characterized. In these coordination polymers, NBPDC and three N-donor ligands link different metal ions and SBUs to construct diverse architectures. Compounds 1 and 3 are isomorphic, showing a two-fold interpenetrating pcu topology. Compound 2 presents a 2D (4, 4) net. Compound 4 is a hex framework built by the linkage of ligands with infinite rod-shaped SBUs. Compound 5 presents a unprecedented eight-fold interpenetrating sra topology. Compound 6 exhibits a unique 2D {6 3}{65.8} topology with four-fold interpenetrating structure. Compound 7 presents a 3D hex topology, and compound 8 shows a (4, 4) net. The magnetic properties of compounds 1, 4, and 7 have been characterized. Compound 1 displays interesting spin-canting antiferromagnetism and metamagnetism simultaneously. Compound 7 exhibits spin-canting antiferromagnetism. The Royal Society of Chemistry 2012.
