“…[22,23] In general, the magnetic exchange interactions decrease rapidly with increasing M···M separations and the experimentally determined J values approach the values predicted by the Coffman Buettner relation (|J| Յ 1 cm -1 for d(M···M) Ն 9 Å). [23,49] Cano et al have shown that this finding also applies to other paramagnetic metal ions, [26] and the interdimer exchange couplings of the present complexes (|J| Յ 0.1 cm -1 , d(Ni 2 ···Ni 2 ) 8.623-11.155 Å) are in good agreement with the reported trend. There seems to be no dependence of the interdimer coupling on the mutual orientation of the Ni 2 O 2 planes, which is in line with our previous observations.…”

“…In this regard, it is worth noting that very weak exchange interactions have indeed been reported for other terephthalato-or isophthalato-bridged nickel(II) complexes. [26,44,45] In order to determine the magnitude of the exchange interactions, the magnetic susceptibility data were simulated by using Equation (1), where χ tetra and χ mono refer to the molar susceptibilities of a Ni 4 complex and a fraction ρ of a mononuclear nickel(II) impurity with Curie constant C = Ng 2 µ B 2 /3kT.…”

“…The magnetic interaction between the cobalt() ions should be very weakly antiferromagnetic and can be neglected since the tp bridge is long. [16] The extent of magnetic coupling of the two adjacent NO groups depends on their separation and the relative orientation of the π* orbitals. [17] In complex 1, the shortest OϪO separation between the nitroxide groups is rather large (3.860 Å ) and the planes of the π systems of the nitroxide radicals form an angle of 26.8°with the plane defined by the two adjacent NO groups.…”

“…In this context, an enormous amount of literature has been generated concerning the distance dependence of magnetic exchange interactions between metal atoms linked by extended dicarboxylate ligands. Dinuclear copper complexes bridged by oxalate [20, 21] and terephthalate [22][23][24] dianions form, by far, the largest group of such systems, and it appears that the exchange interactions depend on the M···M distance [25], the relative orientation of the magnetic orbitals [26], and the degree of conjugation of the organic spacer unit [27, 28]. …”
