“…The fitting process for this expression was very good, and the magnetic parameters obtained were (for g"2.09 and z"4): H"1000 G: From these results, an antiferromagnetic coupling between the unpaired electrons of the Cu(II) atoms involved in the constructing tetranuclear unit of the network previously proposed before can be suggested. The theoretical values from the corresponding equation (22) are shown in Fig. 8b together with the experimental data for H"10,000 G. From this approximation, one finds that J #J #J is slightly lower than J , in agreement with the low symmetry considered for the distorted bidimensional metallic network suggested for this Cu(II) compound.…”

“…This step was performed by employing the orca_eca utility of ORCA on both the experimental and theoretical data. The susceptibility derived from the Van Vleck equation is given by Equation :

\begin{matrix} left \\ χ T = \frac{N g^{2} μ_{B}^{2}}{k} \frac{A}{B} \\ A = 10 \exp (- E_{Q} / k T) + 2 (\exp (- E_{T 1} / k T) + \exp (- E_{T 2} / k T) + \exp (- E_{T 3} / k T)) \\ B = 5 \exp (- E_{Q} / k T) + \exp (- E_{S 1} / k T) + \exp (- E_{S 2} / k T) + 3 (\exp (- E_{T 1} / k T) + \exp (- E_{T 2} / k T) + \exp (- E_{T 3} / k T)) \end{matrix}

A tetranuclear copper(II) complex (1) was synthesized using 2-hydroxy-N-(quinolin-8-yl)acetamide ligand. Singlecrystal X-ray diffraction studies revealed that the complex consists of a distorted Cu 4 O 4 core in which the four copper(II) ions are linked by alkoxo bridges. X-ray analysis also evidenced intramolecular noncovalent carbonyl-π interactions. Those interactions that are encountered between lone-pair electrons (of the amide oxygen atoms here) and π* orbitals of aromatic rings, [a]

“…In cubes, magnetic orbitals of metal ions are accidentally orthogonal to each other and this leads to molecules having high-spin ground states [15][16][17][18][19]. Recently, we found that Schiff base ligands bridge four metal ions to construct cubane core structures [20][21][22][23][24].…”

Reactions of Schiff bases with copper(II), nickel(II), iron(II) and manganese(II) sources yielded tetranuclear complexes of [Cu 4 (Hhsae) 4 ] (3) and [Mn 4 (sap) 4 (MeOH) 4 ]$H 2 O (4), (H 3 hsaeZ2-(4-hydroxysalicylideneamino)-1-ethanol, H 2 saeZ2-salicylideneamino-1-ethanol, H 3 sapdZ2-salicylideneaminopropane-2-methyl-1,3-propanediol, and H 2 sapZ3-salicylideneamino-1-propanol), respectively. Complexes 1-4 have cubane core structures, in which four metal ions are bridged by alkoxides. Magnetic susceptibility measurements revealed that 1-3 have high-spin ground states of SZ2, 4 and 8, respectively, while 4 has a diamagnetic ground state. q
