Effect of pendant arm position and length on the structure and properties of nickel aromatic dicarboxylate coordination polymers incorporating a kinked organodiimine

Hydrothermal synthesis has afforded coordination polymers incorporating 4,4′-dipyridylamine (dpa) and flexible pendant arm aromatic dicarboxylate ligands. [Ni(1,2-phda)(dpa)(H2O)]n (1,2-phda = 1,2-phenylenediacetate) displays rhomboid grid 2D layers. {[Ni(hmph)(dpa)] · 1.33H2O}n (hmph = homophthalate) possesses (6,3) herringbone style 2D coordination layer motifs. [Ni(1,3-phda)(dpa)(μ-H2O)0.5]n (1,3-phda = 1,3-phenylenediacetate) manifests a 3D canted primitive cubic type coordination polymer lattice featuring antiferromagnetically coupled dinuclear kernels.
