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.

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.

The title compound, [Zn(C8H6N4O3)]nor [Zn(L)]n[H2Lis 3-(6-oxo-6,9-dihydro-1H-purin-1-yl)propionic acid], crystallized as a nonmerohedral twin. The ZnIIcation is four-coordinated, ligated by two carboxylate O atoms from twoLligands and two N atoms from another two ligands. Each ligand bridges four ZnIIcentres, extending the structure into a three-dimensional polymer with a 4-connected (65,41) topological structure containing two-dimensional homochiral layers constructed from one-dimensional metal–organic helices. Investigation of the thermal stability of the compound shows that the network has very high thermostability and is stable up to 720 K.
