Abstract:
The title complex, [Fe(C(6)H(4)N(5))(2)(H(2)O)(2)], was synthesized by the reaction of ferrous sulfate with 5-(2-pyrid-yl)-2H-tetra-zole (HL). The Fe(II) atom, located on a crystallographic center of inversion, is coordinated by four N-atom donors from two planar trans-related deprotonated L ligands and two O atoms from two axial water mol-ecules in a distorted octa-hedral geometry. The Fe(II) mononuclear units are further connected by inter-molecular O-H⋯N and C-H⋯O hydrogen-bonding inter-actions, forming a three-dimensional framework.

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...
