“…For this model, least-squares best-fit parameters are J = −2.5 cm –1 , g = 2.01, and R = 3.0 × 10 –5 . The theoretical curve (solid line in Figure ) have fit the experimental data properly, with the J value similar to the average values found in the literature ( J values in the range of −0.95 to −5.6 cm –1 ) for linear trimanganese(II) bridged by carboxylate units. − …”

A family of four M(II)-metal–organic frameworks of general formula {[M x (pvb)2x ]·y(dmf)} n (M = Cu, 1; M = Co, 2; M = Ni, 3; M = Mn, 4), based on the bis{4-[2-(4-pyridyl)ethenyl]} benzoic acid (Hpvb) ligand, were obtained. 1 exhibits a 5-fold interpenetrated lvt framework, 2 and 3 a 7-fold interpenetrating dia framework, and 4 a 2-fold interpenetrated dmc framework. Magnetic properties of 1–4 have been investigated. 1 was analyzed by a Curie–Weiss model, while 2 and 3 where analyzed by a zero-field splitting model due to the very long metal–metal distances, which results in very weak antiferromagnetic interactions. The coupling pathway in 4 was done by carboxylate bridges instead of the pvb pathway, affording a short metal–metal separation that was analyzed by a isotropic Heisenberg spin Hamiltonian for a linear trinuclear Mn(II) cluster. The different metal coordination modes and geometries, along with template effects induced by the solvent, play an important role in the formation of distinctive structural topologies.
