“…As 1 – 4 are isostructural, the differences in these values must be related to the nature of the lanthanide. Similar weak interactions have been found in other ruthenium–gadolinium complexes …”

Attempts to obtain pure crystalline phases of heteropolynuclear diruthenium–lanthanide complexes were made through four different experimental procedures: a conventional method, solvothermal synthesis, solvothermal synthesis assisted by microwave irradiation and layering synthesis. The complexes [Ln(H2O)4][Ru2(CO3)4(H2O)]·xH2O [Ln = Gd, x = 2.5 (1); Ln = Nd, x = 4 (2); Ln = Eu, x = 2.25 (3); Ln = Yb, x = 2.5 (4)] were obtained in good yields through the different procedures, but the layering method was the best to yield single crystals of 1, 3 and 4. In the solvothermal synthesis of 1, the minor product K3[Gd(H2O)4]2[Ru2(CO3)4]3·3.5H2O (5) was also obtained in a very low yield. The crystal structures of the three‐dimensional compounds 1 and 3–5 were determined by single‐crystal X‐ray diffraction, and two different structural types were found for the Gd derivatives. The magnetic properties of 1, 2 and 4 were fitted with an equation including the sum of the molar susceptibilities of the diruthenium unit and the lanthanide ion. However, the fit of the magnetic properties of 3 requires the consideration of the existence of the splitting of the 7F ground‐state term by spin–orbit coupling. This study shows that the magnetic behaviours of 1, 2 and 4 are governed by weak antiferromagnetic interactions between the diruthenium units and the lanthanide ions.

“…Because various ligands show different abilities for mediating electronic effects between copper ions, these coordination compounds display rich magnetic behaviour over various temperature ranges (Rao et al, 2004;Seti® et al, 2006;Chen et al, 2006;Das et al, 2006;Tao et al, 2006). Efforts to obtain new compounds in which rare earth ions are coupled magnetically to transition metal ions and/or organic radicals are increasing rapidly (Mishra et al, 2005;Mori et al, 2005Mori et al, , 2006Costes, Auchel et al, 2006;Murugesu et al, 2006;Yeung et al, 2006). However, it is dif®cult to clarify what contributes most to the magnetic interaction between rare earth and transition metal ions, because a change in magnetic properties depends on many factors.…”

The title compound, diaqua-1kappaO,3kappaO-di-mu-hydroxido-1:2kappa(2)O:O,2:3kappa(2)O:O-di-mu-methacrylato-1:2kappa(2)O:O',2:3kappa(2)O:O'-bis(1,10-phenanthroline)-1kappa(2)N,N';3kappa(2)N,N'-tricopper(II) dinitrate dihydrate, [Cu(3)(C(4)H(5)O(2))(2)(OH)(2)(C(12)H(8)N(2))(2)(H(2)O)(2)](NO(3))(2) x 2 H(2)O, has the central Cu atom on an inversion centre. The three Cu(II) atoms are in a linear arrangement linked by methacrylate and hydroxide groups. The coordination environments of the Cu(II) ions are five-coordinated distorted square-pyramidal for the outer Cu atoms and four-coordinated square-planar for the central Cu atom. All nitrate ions, hydroxide groups and water molecules are linked by hydrogen bonds, forming a linear structure. The complex exhibits ferromagnetic exchange coupling, which is helpful in elucidating magnetic interactions between copper ions and other metallic ions in heteronuclear complexes.

“…As one of the most important magnetic systems, cyanide-bridged complexes have received much attention since their molecular topologies and magnetic coupling between neighboring metal centers through the cyanide bridge can be relatively easily controlled and predicted. A large number of cyanide-bridged molecule-based magnetic materials with high-T c , acting as single-molecule magnets (SMMs), single-chain magnets (SCMs), and spin crossover (SCO) systems, and photomagnetic materials with different types of structures have been synthesized based on about twenty cyanide-containing precursors with or without peripheral organic ligands [4][5][6][7][8][9][10][11][12][13][14][15][16].…”

Four pyridinecarboxamide iron dicyanide building blocks and one Mn(III) compound have been employed to assemble cyanide-bridged heterometallic complexes, resulting in a series of trinuclear cyanide-bridged Fe III -Mn II complexes: (4) (bpb 2-= 1,2-bis(pyridine-2-carboxamido)benzenate, bpmb 2-= 1,2-bis(pyridine-2-carboxamido)-4-methylbenzenate, bpdmb 2-= 1,2-bis(pyridine-2-carboxamido)-4, 5-dimethyl-benzenate, bpClb 2-= 1,2-bis(pyridine-2-carboxamido)-4-chloro-benzenate). Single-crystal X-ray diffraction analysis shows their similar sandwich-like structures, in which the two cyanide-containing building blocks act as monodentate ligands through one of their two cyanide groups to coordinate the Mn(II) center. Investigation of the magnetic properties of these complexes reveals antiferromagnetic coupling between the neighboring Fe(III) and Mn(II) centers through the bridging cyanide group. A best fit to the magnetic susceptibilities of complexes 1 and 3 gave the magnetic coupling constants J = -1.59(2) and -1.32(4) cm -1 , respectively.
