N. Okabe and Y. Muranishi

Abstract: In the title compound, [Fe(C₁₀H₇NO₃)₂(H₂O)₂]₂·C₁₀H₇NO₃·2H₂O, two cis-diaquabis(quinoline-2-carboxylato)iron(II) molecules, one free quinoline-2-carboxylic acid molecule and two water molecules are present in the asymmetric unit. In the complex, the central Fe^II ion has a distorted octahedral coordination geometry, involving two N and two O atoms of the two bidentate organic ligands, together with two aqua O atoms in a cis configuration.
