Abstract: In the title compound, Na[Cr(C₄H₅NO₄)₂]·1.5H₂O, the Cr^III-centered complex anion displays an octahedral coordination geometry formed by two facial iminodiacetate dianions, with two N atoms in a cis configuration. The Na⁺ ion is surrounded by one water and five carboxyl O atoms, with Na-O distances of 2.3221 (15)-2.5531 (18) Å. There is an extensive hydrogen-bonding network in the crystal structure.
