Bis[μ-3,5-bis-(2-pyrid-yl)pyrazolato]bis-(hydrogensulfato)-dicopper(II) methanol disolvate
Abstract:
The title compound, [Cu(2)(C(13)H(9)N(4))(2)(HSO(4))(2)]·2CH(3)OH, consists of discrete centrosymmetric dinuclear complex mol-ecules and methanol solvent mol-ecules. The Cu(II) atom shows a square-pyramidal coordination geometry and is bonded to four N atoms of the two bis-chelating 3,5-bis-(2-pyrid-yl)pyrazol-ate ions (bpypz(-)) and one O atom of the hydrogensulfate ion. The bpypz(-) ligands in the complex mol-ecule are virtually coplanar [dihedral angle between the mean ligand planes = 0.000(1)°] with the Cu(II) atom deviating in opposite directions from their best plane by 0.2080 (12) Å. π-π stacking inter-actions between the pyridyl and pyrazole rings [centroid-centroid distance = 3.391 (3) Å] and strong O-H⋯O hydrogen bonds between the hydrogensulfate ligands and the methanol mol-ecules assemble the mol-ecules into a one-dimensional polymeric structure extending along the a axis. The methanol mol-ecule acts both as an accepter and a donor in the hydrogen bonding.

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.
