Abstract:
In the title compound [systematic name: aqua(1,10-phenanthroline-kappa(2)N,N')(pyridine-2,6-dicarboxylato-kappa(3)O(2),N,O(6))manganese(II) monohydrate, [Mn(C(7)H(3)NO(4))(C(12)H(8)N(2))(H(2)O)].H(2)O, the manganese(II) centre is surrounded by one bidentate phenanthroline ligand [Mn-N = 2.248 (3) and 2.278 (3) A], one tridentate dipicolinate ligand [Mn-N = 2.179 (3) A, and Mn-O = 2.237 (2) and 2.266 (2) A] and one water molecule [Mn-O = 2.117 (3) A], and it exhibits a strongly distorted octahedral geometry, with trans angles ranging from 144.12 (9) to 158.88 (11) degrees. Extensive intermolecular hydrogen-bonding interactions involving coordinated and uncoordinated water molecules and the carboxyl O atoms of the dipicolinate ligand, as well as a stacking interaction involving the phenanthroline rings, are observed in the crystal structure.

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.
