Bis{N-[2-hy-droxy-1,1-bis-(hy-droxy-methyl)eth-yl]glycinato-κ(3) O,N,O'}iron(II).

In the title compound, [Fe(C6H12NO5)2], the Fe(II) ion lies on an inversion center and is coordinated by two N atoms and four O atoms from two tridentate N-[2-hy-droxy-1,1-bis-(hy-droxy-methyl)eth-yl]glycine ligands, forming a slightly distorted octa-hedral coordination environment. In the crystal, O-H⋯O, O-H⋯N and weak C-H⋯O hydrogen bonds link mol-ecules, forming a three-dimensional network.
