A series of metal phosphonates, namely, [Cu(HL)(H2O)] (1), [Cu5(L)2(OH)4]·H2O (2), [Zn3(L)2(H2O)] (3), [Zn3(L)2(phen)2(H2O)2] (4), [Cd3(L)2(H2O)2] (5), [Cd2(L)(OH)(H2O)1.5] (6), and [Cd(HL)(phen)2]·2.5H2O (7), where H3L = 2′-carboxybiphenyl-4-ylmethylphosphonic acid, and phen = 1,10-phenanthroline, have been synthesized under hydrothermal conditions. Compound 1 exhibits a 2D layer structure with the 4-connected (42·64) topology. Compound 2 shows a 2D (3,10)-connected (32·6)(38·48·512·69·74·84) topology. Compound 3 displays a 2D (3,6)-connected (42·6)2(47·66·82) topology. Compound 4 is a 3D framework with the (42·6)2(47·66·82) topology. Compound 5 shows a 2D (4,6)-connected (44·62)(46)(410·65) topology. Compound 6 exhibits a 2D (3,6)-connected (42·6)(46·66·83) topology. Compound 7 displays a 0D closed loop structure. Furthermore, compounds 1, 5 and 7 are consolidated by the intramolecular O–H⋯O hydrogen bonds. All the compounds have been characterized by infrared spectra (IR), elemental analyses, powder X-ray diffraction (PXRD) and thermogravimetric (TG) analyses. The luminescent properties of 3–7 have also been studied.
