Abstract:
The asymmetric unit of the title compound, [MnI(C(8)H(6)N(4))(2)(H(2)O)]I·H(2)O, consists of a cationic Mn(II) complex, an I(-) anion and a solvent water mol-ecule. In the complex, the Mn(II) ion is six-coordinated in a distorted octa-hedral environment defined by four N atoms of the two chelating 2,2'-bipyrimidine (bpym) ligands, one I(-) anion and one O atom of a water ligand. The dihedral angle between the least-squares planes of the two bpym ligands [maximum deviation = 0.092 (7) Å] is 79.9 (1)°. In the crystal, the complex, anion and solvent water mol-ecule are linked by inter-molecular O-H⋯O, O-H⋯I and O-H⋯N hydrogen bonds.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...

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.
