Five transition-metal coordination polymers, namely, [Zn{sub 7}Cl{sub 6}(oba){sub 4}]{sub n} (1), [Cd{sub 7}Cl{sub 6}(oba){sub 4}]{sub n} (2), [Zn(oba)(H{sub 2}O)]{sub n} (3), [Ag{sub 2}(oba)]{sub n} (4) and [Co(oba)(H{sub 2}O){sub 2}]{sub n} (5) (H{sub 2}oba=4,4′-oxydibenzoic acid), have been achieved under hydrothermal conditions and structurally characterized by IR, elemental analyses, X-ray single-crystal diffraction and TGA. The X-ray single-crystal diffraction reveals that compounds 1 and 2 are isomorphism, featuring pillared-layer 3D motifs, in which the 2D inorganic layers (Zn{sub 6}Cl{sub 7}){sub n} (or (Cd{sub 6}Cl{sub 7}){sub n}) are connected by oba{sup 2−} pillars. Compound 3 exhibits 1D stair-like chain and extends to a 3D network by two different interchain O–H–O hydrogen bonding interactions while compound 4 features wave chains and stretches to 2D layer by interchain Ag–O weak contacts. Compound 5 shows 2D network in which Co-chains are pillared by oba{sup 2−} ligand and then forms a 3D network by four different O–H–O hydrogen bonding interactions. Furthermore, 1–4 exhibit luminescent properties at a solid state and 5 shows antiferromagnetic behavior. - Graphical abstract: Five new transition-metal coordination complexes 1–5 have been synthesized and characterized by single-crystal X-ray diffractions, IR spectra, elemental analyses, thermogravimetric analyses (TGA), photoluminescent spectra and magnetic measurement. - Highlights: • Compound 1 exhibits a pillared-layer 3D network. • The photoluminescent properties of 1–4 have been measured. • Compound 5 exhibits antiferromagnetic behavior.
