Popis: A new series of four coordination polymers of alkali metals (Li, Na, and K) was assembled from a poorly explored building block, biphenyl-4,4′-dioxydiacetic acid (H2L), and characterized by FTIR-ATR, TG-DSC, elemental analysis, and single crystal X-ray diffraction methods. The obtained structures range from 2D coordination polymers [Li2(µ-L)(µ-H2O)2(H2O)2] (1) and [Na2(µ4-L)(µ-H2O)2(H2O)2] (2) to 3D metal-organic frameworks [Na2(µ6-L)(µ-H2O)2] (3) and [K2(µ10-L)] (4). The influence of metal ionic radii on the crystal structures of the coordination polymers and conformation of the flexible biphenyl-4,4′-dioxydiacetate ligand was analyzed. Structural complexity increases within the series of products 1–4 following the Li
