A family of new lanthanide compounds [Ln(HBIC)3]n [Ln = Ce (1), Dy (2), Er (3); H2BIC = 1H‐benzimidazole‐2‐carboxylic acid] was obtained under hydrothermal conditions and characterized by elemental analysis, IR, X‐ray single crystal diffraction, thermal and luminescent analyses. X‐ray single crystal diffraction shows that compounds 1–3 are isotypic and exhibit 2D networks constructed by bridging‐chelating HBIC– linkers and lanthanide ion nodes, in which each central lanthanide atom is surrounded by five flexible HBIC– ligands with two kinds of new coordination modes, yielding a distorted two‐capped triangle prism arrangement. Moreover, the thermal and photoluminescence properties of 1–3 were also investigated.
