“…In many complexes of the first‐ and second‐row26,27 transition metals, and in all lanthanide and actinide complexes,16 the ligand oda adopts a tridentate planar coordination mode. The non‐planar arrangement of the ligand (II in Scheme ) is uniquely found in some six‐coordinate oxydiacetate compounds of nickel( II ) and copper( II ) 10,13,14. We have previously suggested and theoretically supported12,15 the idea that the precise position of the C−O−C antisymmetric stretching band is diagnostic of the oda disposition in the various complexes.…”

“…Compound 2 is also a polymer, in contrast with the related monomeric compounds [M(oda)(phen)(H 2 O)] (M = Ni,10 Zn9). Each metal ion in 2 is six‐coordinated by the three oxygen atoms of one oda ligand in the planar disposition, by the phen chelate and by an oxygen atom of a oda carboxylate group belonging to a symmetry repeated {Mn(oda)(phen)} unit (Figure 4, a).…”

“…The ligand usually behaves as tridentate monometallic. Two possible isomers, I or II, are known, for which the ligand oda is overall planar6−12 or puckered, respectively 10,13,14. In six‐coordinate complexes, these isomers are referred to as mer or fac , respectively.…”

The aerobic aqueous solution syntheses and structures of monomeric and polymeric MnII complexes containing the oxydiacetate ligand [O(CH2COO)22− = oda] are reported. The magnetic properties of the polymeric products have also been investigated. The initially obtained species [{Mn(oda)(H2O)}·H2O]n (1) has been reacted with bidentate or tridentate N‐donor ligands such as o‐phenanthroline (phen), 2,2′‐bipyridine (bipy) and 2,2′:6,2′′‐terpyridine (terpy) to give the complexes [{Mn(oda)(phen)}·4H2O]n (2), [Mn(oda)(bipy)(H2O)]·2H2O (3) and [Mn(oda)(terpy)]·2H2O (4), respectively. Species 1−4 are the first Mn‐oda structures determined by X‐ray methods. In all cases, the oda acts as a tridentate ligand toward one metal and adopts the typical planar arrangement. However, while the 3 and 4 are monomers, 2 and 1 are polymers as oda exploits both atoms of its carboxylate groups to coordinate other metals; 1 consists of a three‐dimensional diamond‐type network, while 2 is one‐dimensional, consisting of an extended chain of {Mn(oda)(phen)} subunits. For both compounds, magnetic susceptibility measurements down to 2 K showed only weak antiferromagnetic interactions between high‐spin MnII ions. Despite the expectedly similar coordinating capabilities of N‐donor ligands, the bipy complex 3 is a monomer with the six‐coordination completed by one water ligand. The tridentate nature of simultaneously present oda and terpy ligands excludes the coordination of water in complex 4, the geometry of which is distorted from the octahedron, most likely due to a peculiar packing effect. Finally, the known five‐coordinate complex [MnCl2(terpy)] (5), a side product of our synthetic experiments, has also been structurally characterized. (© Wiley‐VCH Verlag GmbH & Co.

Bonding interactions in oxydiacetate and thiodiacetate cobalt(II) and nickel(II) complexes

The influence of the central donor atom of the oxydiacetate and thiodiacetate ligands (oxygen and sulphur atoms, respectively) on the thermodynamic parameters for complexation reactions of the Co 2+ and Ni 2+ ions has been investigated using the isothermal titration calorimetry (ITC) technique and density functional theory (DFT) computations. The polarized continuum (PCM) -solvation model was employed to describe the structural factors that govern the coordination modes of the ligands (mer or fac) in the solution. The differences in the binding enthalpies of the investigated complexes were discussed based on the results obtained both from the natural bond orbital (NBO) analysis and the secondorder perturbation theory.
