Abstract: The crystal structure of Na₂[Co(Hida)₂]. 6H₂O (Hida = iminodiacetato) contains discrete units [Co(Hida)₂]^2-, ions Na⁺, and water molecules. The pseudooctahedral coordination of Co(II) is created by four O atoms (the bond lengths Co-O are 0.202(1), 0.203(1), 0.207(1), and 0.210(1) nm) and two N atoms of two Hida ligands (bond lengths Co-N are 0.211(2) and 0.214(2) nm). The cations Na+ are pseudooctahedrally surrounded by four water O atoms and two carboxyl O atoms from the different units [Co(Hida)₂]^2-.
