Crystal structure of bis(1,3-bis{[(1H-pyrrol-2-yl)methylidene]amino-κN}propan-2-olato-κO)manganese(III) nitrate methanol monosolvate

چکیده
The asymmetric unit of the title compound, [Mn(C13H15N4O)2]NO3·CH3OH, contains two independent complex cations, in each of which the Mn(III) ion is located on an inversion centre. The Mn(III) ion is coordinated by four N and two O atoms from two 1,3-bis-{[(1H-pyrrol-2-yl)methyl-idene]amino}-propan-2-olate ligands, resulting in a distorted octa-hedral geometry. The average Mn-ligand bond lengths in the two complex mol-ecules are 2.074 and 2.079 Å. In the crystal, inter-molecular N-H⋯O hydrogen bonds between the pyrrole group of the ligand and the non-coordinating nitrate ion give rise to a chain structure along [10-1]. The methanol solvent mol-ecule and the nitrate ion are connected by an O-H⋯O hydrogen bond.

The reaction of manganese seleno-cyanate with 1,2-bis-(pyridin-4-yl)ethane (bpa) leads to the title compound, {[Mn(NCSe)2(C12H12N2)(CH3OH)2]·C12H12N2} n . The Mn(II) cation is coordinated by two N-bonded seleno-cyanate anions, two bpa ligands and two O-bonded methanol mol-ecules, within a slightly distorted octa-hedral geometry. The Mn(II) cations and the non-coordinating N-donor ligands are lo...

The whole mol-ecule of the title compound, [Mn(NCS)2(CH3OH)2(C5H6N2)2], is generated by inversion symmetry. The Mn(II) ion, which is located on an inversion center, is coordinated by two 4-(di-methyl-amino)-pyridine ligands, two methanol ligands and two terminally N-bonded thio-cyanate anions, forming a slightly distorted octa-hedron. In the crystal, mol-ecules are linked by O-H⋯S hydrogen bond...
