| Özet |
| In the title centrosymmetric complex, [Mn(C10 H11 O2)2 (C10 H14 N2 O)2 (H2 O)2 ], the Mn II cation is located on an inversion centre. The four O atoms form a slightly distorted square-planar arrangement around the Mn II cation, and the distorted octahedral coordination is completed by two pyridine N atoms at distances of 2.3289(15)Å. The dihedral angle between the planar carboxylate group and the adjacent benzene ring is 87.73(16)°, while the benzene and pyridine rings are oriented at a dihedral angle of 43.03(8)°. In the crystal, the water molecules are involved in both intramolecular (to the non-coordinating carboxylate O atom) and intermolecular (to the amide carbonyl O atom) O - H...O hydrogen bonds. The latter lead to the formation of layers parallel to (100). These layers are further linked via weak C - H...O hydrogen bonds, resulting in a three-dimensional supramolecular network. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H...H (70.0%), H...O/O...H (15.5%) and H...C/C...H (14.0%) interactions. One of the ethyl groups of the diethylnicotinamide ligand is disordered over two sets of sites, with an occupancy ratio of 0.282(10):0.718(10). |
