Abstract: In the title complex, [La(NO₃)₂(bib)₂(H₂O)₂]·0.5bib·H₂O [bib is 1,4-bis(1-imidazolyl)benzene, C₁₂H₁₀N₄], the La^III atom is coordinated by two N atoms from two bib ligands and eight O atoms from three nitrate and two water ligands. This mononuclear complex is further extended into a three-dimensional structure via hydrogen bonds with free bib and water molecules of crystallization, the former lying on inversion centers.
