Diaqua-bis(4-methyl-benzoato-κO)bis-(nicotinamide-κN)manganese(II)
Abstract:
In the mononuclear title complex, [Mn(C(8)H(7)O(2))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(2)], the Mn(II) ion is located on a crystallographic inversion center. The asymmetric unit contains one 4-methyl-benzoate anion, one nicotinamide (NA) ligand and one coordinated water mol-ecule. The four O atoms in the equatorial plane around the Mn(II) ion form a slightly distorted square-planar arrangement, while the slightly distorted octa-hedral coordination is completed by the two pyridine N atoms of the NA ligands in the axial positions. The dihedral angle between the carboxyl-ate group and the attached benzene ring is 9.01 (7)°, while the pyridine and benzene rings are oriented at a dihedral angle of 42.44 (5)°. In the crystal structure, inter-molecular O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds, and O-H⋯π and C-H⋯π inter-actions link the mol-ecules into a two-dimensional network parallel to (001).

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.
Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
