In the title mixed-ligand complex, [Mn(C7H4NO4)2(C12H12N2)2(H2O)2], was synthesized and its crystal structure was studied. The Mn atom is six-coordinated in slightly distorted octahedral coordination geometry by two N atoms of two 1,2-di-4-pyridylethane ligands (L), two O atoms of monodentate 2-nitrobenzoate ligands and two O atoms of water molecules. The Mn atom is located on a centre of inversion. A one-dimensional structure is formed in the [101] direction by intermolecular hydrogen bonds between the aqua ligands and N atoms of L. An intramolecular hydrogen bond between the other aqua ligand and a neighbouring O atom of a carboxylate group is also observed.

Special details top
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes)
are estimated using the full covariance matrix. The cell e.s.d.'s are taken
into account individually in the estimation of e.s.d.'s in distances, angles
and torsion angles; correlations between e.s.d.'s in cell parameters are only
used when they are defined by crystal symmetry. An approximate (isotropic)
treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s.
planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor
wR and goodness of fit S are based on F2, conventional
R-factors R are based on F, with F set to zero for
negative F2. The threshold expression of F2 >
σ(F2) is used only for calculating R-factors(gt) etc.
and is not relevant to the choice of reflections for refinement.
R-factors based on F2 are statistically about twice as large
as those based on F, and R- factors based on ALL data will be
even larger. |
