Five new coordination polymers, {l_brace}[Cd{sub 3}(bpt){sub 2}(DMF){sub 2}]{center_dot}(H{sub 2}O){sub 2}{r_brace}{sub n} (1), [Cd(Hbpt)(bipy){sub 0.5}(H{sub 2}O)]{sub n} (2), [Cd{sub 2}(bpt)(phen){sub 2}Cl]{sub n} (3), {l_brace}[Cu{sub 2}(bpt)(phen)({mu}{sub 2}-OH)(H{sub 2}O)]{center_dot}(H{sub 2}O){sub 2}{r_brace}{sub n} (4) and {l_brace}[Mn{sub 5}(Hbpt){sub 4}(phen){sub 4}({mu}{sub 2}-OH){sub 2}(H{sub 2}O){sub 2}]{center_dot}(H{sub 2}O){sub 2}(CH{sub 3}CN){sub 2}{r_brace}{sub n} (5) have been prepared through hydro(solvo)thermal reactions of H{sub 3}bpt (H{sub 3}bpt=biphenyl-3,4 Prime ,5-tricarboxylic acid) with different pyridyl-containing auxiliary ligands (bipy=4,4 Prime -bipyridine and phen=1,10-phenanthroline). Compound 1 represents a 3D ladder-like framework composed of rod-shaped infinite chains. In 2, the bridging ligand bipy links binuclear cadmium ions to generate a 2D layer. Compound 3 features a 1D ladder structure and further linked by {pi}-{pi} stacking interaction to form a 3D supramolecular network. Compound 4 exhibits a binodal 3-connected net which features the Schlafli symbol of (4{center_dot}8{sup 2}). Compound 5 contains trimetallic cluster and binuclear unite which are further linked by Hbpt ligand to form a 2D layer. Moreover, photoluminescent properties of compounds 1-3 were studied in the solid state. Magnetic susceptibility measurements indicate that compound 4 exhibits ferromagnetic exchange interactions, whereas compound 5 displays antiferromagnetic exchange interactions. - Graphical abstract: Five new coordination polymers have been prepared through reactions of H{sub 3}bpt with different pyridyl-containing auxiliary ligands. The bpt exhibits four new kinds of coordination modes with 'V or Y shape'. Highlights: Black-Right-Pointing-Pointer 1 represents a unique (4{center_dot}8)-connected network with a Schlafli symbol (4{sup 6})(4{sup 12}{center_dot}6{sup 12}{center_dot}8{sup 4}). Black-Right-Pointing-Pointer Compound 4 shows ferromagnetic interaction between the dimeric Cu{sup 2+} units. Black-Right-Pointing-Pointer The bpt ligand exhibits four new kinds of coordination modes with 'V or Y shape'.
