{2-[(2-Acetyl-hydrazin-1-yl-idene)methyl-κN,O]-6-methoxy-phenolato-κO}(nitrato-κO)copper(II) monohydrate
Abstract:
In the title complex, [Cu(C(10)H(11)N(2)O(3))(NO(3))]·H(2)O, prepared from the Schiff base N'-(3-meth-oxy-2-oxidobenzyl-idene)-acetohydrazide, the Cu(II) atom is coordinated by two O atoms and one N atom from the ligand and one O atom from a nitrate group in a distorted square-planar geometry. The Cu(II) atom has a weak inter-action with another O atom of the nitrate group. The two O atoms of the tridentate Schiff base ligand are in a trans arrangement. O-H⋯O and N-H⋯O hydrogen bonds involving the uncoordinated water mol-ecule are observed.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
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...
