Diaqua-bis-(4-bromo-benzoato-κO)bis-(N,N-diethyl-nicotinamide-κN)manganese(II)
Abstract:
In the crystal structure of the title Mn(II) complex, [Mn(C(7)H(4)BrO(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], the Mn(II) cation is located on an inversion center and coordinated by two diethyl-nicotinamide (DENA) ligands, two 4-bromo-benzoate (PBB) anions and two water mol-ecules in a distorted octa-hedral geometry. The dihedral angle between the carboxyl-ate group and the adjacent benzene ring is 3.25 (14)°. In the mol-ecule, the pyridine ring and the benzene ring are oriented at a dihedral angle of 77.24 (5)°. In the crystal, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into a two-dimensional network. Weak inter-molecular C-H⋯O hydrogen bonds and π-π inter-actions between the pyridine rings of neighbouring mol-ecules [centroid-centroid distance = 3.537 (1) Å] further consolidate the crystal packing.

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.
