1-Ethyl-1H-pyrazole-4-carboxaldehyde

N-Ethyl-4-fomylpyrazole is a coordination compound that contains an axial ligand. It is a transition metal complex with the general formula M(N=NAr)X, where M is a transition metal, N is the central atom, and Ar is the substituent on the nitrogen atom. This compound exhibits strong magnetic interactions with paramagnetic ions such as Cu(II) and Fe(III). The nature of these interactions can be explained by considering the geometrical arrangement of the ligands in space. The polyhedron around each ion has two faces that are occupied by four ligands (two axial and two equatorial). These ligands form pi-bonds to each other and interact electrostatically through their electrons. The thermally induced nature of these interactions leads to changes in the bond lengths and angles.
