Diammine{N-[2-(hy­droxy­imino)­propion­yl]-N′-[2-(oxidoimino)­propion­yl]propane-1,3-diaminido-κ(4) N,N′,N′′,N′′′}iron(III)

In the title compound, [Fe(C(9)H(13)N(4)O(4))(NH(3))(2)], the Fe(III) atom, lying on a mirror plane, is coordinated by four N atoms of a triply deprotonated tetra­dentate N-[2-(hy­droxy­imino)­propion­yl]-N′-[2-(oxidoimino)­propion­yl]propane-1,3-diaminide ligand in the equatorial plane and two N atoms of two ammonia mol­ecules at the axial positions in a distorted octa­hedral geometry. A short intra­molecular O—H⋯O hydrogen bond between the cis-disposed oxime O atoms stabilizes the pseudo-macrocyclic configuration of the ligand. In the crystal, mol­ecules are linked by N—H⋯O hydrogen bonds into a three-dimensional network. The ligand has a mirror-plane symmetry. One of the methyl­ene groups of the propane bridge is disordered over two sets of sites with equal occupancy factors.
