Abstract:
In the title complex, [Mn(C(8)H(4)O(7)S)(C(12)H(8)N(2))(2)], the Mn(II) atom is chelated by one 4-carb-oxy-2-sulfonato-benzoate anion and two phenathroline (phen) ligands in a distorted octa-hedral MnN(4)O(2) geometry. The benzene ring of the 4-carb-oxy-2-sulfonato-benzoate anion is twisted with respect to the two phen ring systems at dihedral angles of 66.38 (9) and 53.56 (9)°. In the crystal, inter-molecular O-H⋯O and C-H⋯O hydrogen bonding links the mol-ecules into chains running parallel to [100]. Inter-molecular π-π stacking is also observed between parallel phen ring systems, the face-to-face distance being 3.432 (6) Å.

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.

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...
