Two novel coordination polymers, [Cu(H 2 L)(bipy)(H 2 O) 2 ] · H 2 O ( 1 ) and [Ni 2 (H 2 L)(bipy) 2.5 (H 2 O) 6 ] · (H 2 L) · 7H 2 O ( 2 ) with the V‐shaped diphosphonate ligand (2,4,6‐trimethyl‐1,3‐phenylene)bis(methylene)diphosphonic acid (H 4 L) were synthesized via hydrothermal reactions in the presence of auxiliary ligand 4,4′‐bipyridine. Their structures were determined by single‐crystal X‐ray diffraction and further characterized by elemental analysis, infrared spectroscopy (IR), and thermogravimetric analysis (TGA). Compound 1 crystallizes in the Pnma space group and compound 2 crystallizes in the P 2 1 2 1 2 space group. They display square‐grid layer and bilayer two‐dimensional network, respectively.
