Abstract:
In the title compound, [Cu(C(14)H(9)N(2)O(2))(2)]·2H(2)O, the Cu(II) ion lies on a centre of symmetry and is four-coordinated by two N atoms and two O atoms from two 2-(1H-benzimidazol-2-yl)benzoate ligands in a square-planar environment. The benzimidazol and benzyl rings form a dihedral angle of 42.8 (5)°. The mol-ecule contains two H-bonded carboxyl O acceptors and two H-bonded N-H donors in the benzimidazol groups, which inter-act with two symmetry-related uncoordinated water mol-ecules so that neighboring mol-ecular units are linked by (O-H)(water)⋯O(carbox-yl) hydrogen bonds with an R(2) (4)(8) graph-set motif, generating a helical chain in the a-axis direction. These chains are, in turn, inter-connected by (N-H)(benzimidazol)⋯O(water) hydrogen bonds, forming a three-dimensional supra-molecular network.

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.
