Abstract:
In the title compound, {[Cu(2)(C(4)H(2)O(4))(2)(H(2)O)(2)]·3H(2)O}(n), Cu(II) ions with square-pyramidal coordination are bridged by exo-tri-dentate maleate dianions into [Cu(2)(maleate)(2)(H(2)O)(2)](n) layers coincident with the bc crystal plane. The inter-lamellar regions contain hydrogen-bonded cyclic water hexa-mers which facilitate layer stacking into a pseudo-three-dimensional crystal structure. The water hexamers themselves are formed by the operation of crystallographic inversion centers on sets of three crystallographically distinct water molecules of hydration.

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.

Metal-Ligand Bonds
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...
