One-dimensional nickel and cobalt phthalate coordination polymers incorporating the kinked dipodal organodiimine 4,4′-dipyridylamine: Hydrothermal synthesis, structural characterization and thermal properties
چکیده انگلیسی

Hydrothermal synthesis has afforded a family of three structurally related metal phthalate (pht) 1-D coordination polymers incorporating the kinked dipodal organodiimine 4,4′-dipyridylamine (dpa), with a general formulation of [L2M(dpa)2M(H2O)4] · H2O (L = pht, M = Co, 1, M = Ni, 2; L = 4-methylphthalate (4-mpht), M = Co, 3). Single crystal X-ray diffraction of 1 and 2 revealed the presence of one-dimensional (1-D) polymeric chains consisting of [M(H2O)4]2+ and [M(pht)2]2− subunits linked through dpa tethers. These chains in turn conjoin into pseudo 2-D layers and 3-D networks via extensive supramolecular hydrogen bonding pathways. An extremely similar structure is observed for 3 despite the presence of the bulkier methyl group substituent. 1–3 were further characterized via infrared spectroscopy and elemental and thermogravimetric analysis. 1–3 represent the first dicarboxylate coordination polymers incorporating dpa tethering ligands.

Hydrothermal synthesis has afforded two metal phthalate (pht) 1-D coordination polymers incorporating the kinked dipodal organodiimine 4,4′-dipyridylamine (dpa), with a general formulation of [M(pht)2(dpa)2M(H2O)4] · H2O (M = Co, 1; M = Ni, 2). Use of the 4-methylphthalate (4-mpht) anion yields the 1-D coordination polymer [Co(4-mpht)2(dpa)2Co(H2O)4] · H2O, which displays a very similar structure to 1 and 2 despite the bulkier methyl substituent.Figure optionsDownload as PowerPoint slide
