✦ Synopsis
The La^III^ atom in the title complex, [La(NO~3~)~3~(H~2~O)~3~]·2C~10~H~8~N~2~, is irregularly coordinated by three O atoms of three water molecules and six O atoms of three NO~3~
^−^ ligands. This mononuclear complex is further extended into a supramolecular network structure via O—H...O and O—H...N hydrogen bonds.
