Transition metal phosphite complexes: from one-dimensional chain, two-dimensional sheet, to three-dimensional architecture with unusual magnetic properties

The hydrothermal synthesis of the novel complex poly[[μ2-N1,N4-bis(pyridin-3-yl)naphthalene-1,4-dicarboxamide-κ2N3:N3′](μ4-phthalato-κ4O1:O1:O1′:O2′)copper(II)], [Cu(C8H4O4)(C22H16N4O2)]n, is described. With the phthalate ligand connecting neighbouring CuIIcations, an infinite one-dimensional chain is formed. Adjacent one-dimensional chains are connected by the dicarboxamide ligand, forming an intriguing two-dimensional framework. The magnetic properties and thermal stability of this complex are also described.

In the title coordination polymer,catena-poly[[bis[{1-[(1H-benzimidazol-2-yl-κN3)methyl]-1H-tetrazole}zinc(II)]-bis(μ4-pentane-1,5-dioato-1:2:1′:2′κ4O1:O1′:O5:O5′)] methanol disolvate], {[Zn(C5H6O4)(C9H8N6)]·CH3OH}n, each ZnIIion is five-coordinated by four O atoms from four glutarate ligands and by one N atom from a 1-[(1H-benzimidazol-2-yl)methyl]-1H-tetrazole (bimt) ligand, leading to a slightly distorted square-pyramidal coordination environment. Two ZnIIions are linked by four bridging glutarate carboxylate groups to generate a dinuclear [Zn2(CO2)4] paddle-wheel unit. The dinuclear units are further connected into a one-dimensional chainviathe glutarate ligands. The bimt ligands coordinate to the ZnIIions in a monodentate mode and are pendant on both sides of the main chain. In the crystal, the chains are linked by O—H...O and N—H...O hydrogen bonds into a two-dimensional layered structure. Adjacent layers are further packed into a three-dimensional network through van der Waals forces. A thermogravimetric analysis was carried out and the photoluminescent behaviour of the polymer was investigated.

The hydrothermal synthesis of the novel complex poly[aqua(μ4-benzene-1,2,3-tricarboxylato)[μ2-4,4′-(hydrazine-1,2-diylidenedimethanylylidene)dipyridine](μ3-hydroxido)dizinc(II)], [Zn(C9H3O6)(OH)(C12H10N4)(H2O)]n, is described. The benzene-1,2,3-tricarboxylate ligand connects neighbouring Zn4(OH)2secondary building units (SBUs) producing an infinite one-dimensional chain. Adjacent one-dimensional chains are connected by theN,N′-bis[(pyridin-4-yl)methylidene]hydrazine ligand, forming a two-dimensional layered structure. Adjacent layers are stacked to generate a three-dimensional supramolecular architectureviaO—H...O hydrogen-bond interactions. The thermal stability of this complex is described and the complex also appears to have potential for application as a luminescent material.
