Abstract:
In the title compound, [Cu(C(11)H(13)N(3))(2)](NO(3))(2)·2H(2)O, synthesized by hydro-thermal reaction of Cu(NO(3))(2) and racemic 2-(pyrrolidin-2-yl)-1H-1,3-benzimidazole, the Cu(II) atom lies on an inversion centre. The distorted octa-hedral Cu(II) environment contains two planar trans-related N,N-chelating 2-(pyrrolidin-2-yl)-1H-1,3-benzimidazole ligands in the equatorial plane and two monodentate nitrate anions, which are in weak inter-action with the Cu atom, in the axial positions. The two benzimidazole ligands have opposite configurations (R/S and S/R) and compound is a meso complex. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds generate an infinite three-dimensional network. One methylene group of the pyrrolidine ring is disordered over two position with a 0.56 (3):0.44 (3) occupancy.

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.
