Abstract:
In the centrosymmetric dinuclear title complex, [Cu(2)(C(5)H(6)O(4))(2)(C(12)H(18)N(2))(2)(H(2)O)(2)], the Cu(II) atom displays a dis-torted square-pyramidal coordination environment with the basal plane occupied by two phenanthroline N atoms and two O atoms from different glutarate dianions while a water mol-ecule is located at the apical position. Of the two water H atoms, one is engaged in an intra-molecular hydrogen bond with a free oxygen of the dianion whereas the second is engaged in an inter-molecular hydrogen bond, building a corrugated layer parallel to (100). These layers are further connected through π-π stacking inter-actions involving symmetry-related phenanthroline rings [centroid-centroid distance = 3.5599 (17) and 3.5617 (18) Å], building a three dimensionnal network. C-H⋯π inter-actions involving the phenanthroline ring system are also observed.

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...

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.
