چکیده
In the title compound, [Fe(C9H13N4O4)(NH3)2], the Fe(III) atom, lying on a mirror plane, is coordinated by four N atoms of a triply deprotonated tetra-dentate N-[2-(hy-droxy-imino)-propion-yl]-N'-[2-(oxidoimino)-propion-yl]propane-1,3-diaminide ligand in the equatorial plane and two N atoms of two ammonia mol-ecules at the axial positions in a distorted octa-hedral geometry. A short intra-molecular O-H⋯O hydrogen bond between the cis-disposed oxime O atoms stabilizes the pseudo-macrocyclic configuration of the ligand. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds into a three-dimensional network. The ligand has a mirror-plane symmetry. One of the methyl-ene groups of the propane bridge is disordered over two sets of sites with equal occupancy factors.

The title complex, [Cu(2)(C(22)H(20)Br(2)N(4)O(2))(ClO(4))(2)], was prepared by the condensation of 2,6-diformyl-4-bromo-phenol with 1,3-diamino-propane in the presence of copper(II) ions. The macrocyclic ligand shows an approximately planar structure except for the two propene groups in the macrocycle. The coordination polyhedron of each Cu atom can be described as distorted square pyramidal. ...

متن کاملReactivity of methane mono-oxygenase, insights from quantum mechanic studies on synthetic iron model complexes
Methane mono-oxygenase (MMO) and deoxyhemerythrin (DHr) are examples of di-iron enzymes that catalyze the dissociative and non-dissociative binding of molecular oxygen. To mimic the MMO active site with a finite cluster, we chose to study the binuclear heptapodate coordinated iron(III)-complexes of N,N,N′,N′-tetrakis(2-benzimidazolylmethyl)-2-hydroxy-1,3diamino-propane (HPTB) and N,N,N′,N′-tetr...
