N2 - Four novel metal-organic coordination polymers, [Zn2(ppda)(phen) 2(HCOO)2] (1), [Mn(ppda)(phen)(H2O) 2] DMF (2), [Zn(mpda)(phen)] 1.5H2O (3), and [Mn 2(mpda)2(phen)2] (4), (H2ppda ) p-phenylenediacrylic acid, H2mpda ) m-phenylenediacrylic acid, and phen ) 1,10-phenanthroline) have been synthesized under hydrothermal conditions. Compound 1 consists of two-dimensional (2D) bilayers in which formate-bridged chains are cross-linked by ppda ligands, and the bilayers are sustained by infinite zipper-like p-p stacking of the phen ligands. Compounds 2 and 3 are both one-dimensional (1D) coordination polymers, but exhibit different chain shapes due to the different geometry of ppda and mpda. Via O-H- - -O hydrogen bonding and pairwise phen - - - phen p-p stacking, the zigzag chains in 2 are assembled into a three-dimensional (3D) diamond network with 3-fold interpenetration, while the helical chains in 3 are packed into a 3D structure through quadruple p-p stacking arrays. Compound 4 is composed of double twist chains of binuclear units sustained by double carboxylate bridges and phen - - - phen π-π stacking. Magnetic investigations on 2 and 4 have been carried out. Compound 4 exhibits weak intradimer antiferromagnetic exchange mediated through the carboxylate bridges and the possible π-π stacking pathway, while much weaker antiferromagnetic exchange is operative through the interchain hydrogen bonding motif in 2.
