“…Recently, we studied a series of heterometallic 3d–4f complexes containing M 2 Ln cores [M II = Ni, Cu; Ln III = Nd, Pr, Sm, Eu, Gd, Zn 2 Eu, Cu 2 Ln 2 (Ln III = Sm or Gd), Ni II 2 Gd III 2 ] . In the majority of cases, these complexes (or precursors containing their polynuclear cores) formed through self‐assembly reactions in solution.…”

A series of new Co II -Ln III complexes with polynuclear {Co 2 Ln(NO 3 )(Piv) 6 } (Ln = La, Gd, Dy; Piv = pivalate) cores were prepared by self-assembly reactions or step-by-step assembly.[Co 2 Dy(NO 3 )(Piv) 6 (MeCN) 2 ] was used as the starting compound for the synthesis of the trinuclear analogue [Co 2 Dy(NO 3 )(Piv) 6 -(py) 2 ] (py = pyridine) and the pentanuclear complex [{Co 2 Dy-(NO 3 )(Piv) 6 }{CoL(Piv)(H 2 O)} 2 ][NO 3 ] 2 [L = 2,6-bis(2-pyridyl)-4-(4pyridyl)pyridine]. The effects of the coordination environment and temperature on the distortion of the Ln III coordination polyhedra were analyzed for a series of coordination compounds with M II 2 Ln III cores and close analogues. The distortion of the Ln III polyhedron depends on both the composition of [a] N.

“…Since pivalic acid ( pivH) has been shown to be an excellent co-ligand, preventing extensive hydrolysis of the metal centres, for the synthesis of 3d/4f polynuclear CCs, [19][20][21][22][23][24][25] we decided to incorporate it in the reaction system that afforded the two isoskeletal Co II 3 Dy III 4 CCs (1 and 2), resulting in the synthesis of seven new compounds formulated as [Co II 2 Dy III 2 (µ 3 -MeO) 2 (L) 2 -( piv 9) with robust and unprecedented topologies. These show that the temperature and reaction time influence the formation of the final product.…”

Mixing Co(NO3)2·6H2O/Dy(NO3)3·6H2O/(E)-4-(2-hydroxy-3-methoxybenzylideneamino)-2,3-dimethyl-1-phenyl-1,2-dihydropyrazol-5-one (HL)/pivalic acid/Et3N in various solvents results in the synthesis of seven compounds formulated as [CoII2DyIII2(μ3-MeO)2(L)2(piv)4(NO3)2] (3), [CoIIDyIII3(μ3-MeO)2(μ2-MeO)2(L)2(piv)2(NO3)3]·2(CH3OH) (4·2CH3OH), 2[CoII4DyIII4(μ2-O)2(μ3-OH)4(L)4(piv)8][CoII2DyIII5(μ3-OH)6(L)2(piv)8(NO3)4] (5), [CoII4DyIII4(μ2-O)2(μ3-OH)4(L)4(piv)8]·2(CH3CN) (6·2CH3CN), [CoII2DyIII5(μ3-OH)6(L)2(piv)8(NO3)4]·4(CH3CN) (7·4CH3CN), [CoII2DyIII2(μ3-OH)2(L)2(piv)2(NO3)2(EtOH)2(H2O)2](NO3)2·(EtOH) (8·EtOH) and [CoII4DyIII4(μ2-O)2(μ3-OH)4(L)4(piv)8] (9) with robust and unseen topologies. These show that the temperature and reaction time influence the formation of the final product. Preliminary magnetic studies, performed for 6 and 7 in the temperature range 2–300 K, are indicative of Single Molecule Magnet (SMM) behaviour. Moreover, analysis of the catalytic properties of compound 3 as an efficient catalyst for the synthesis of trans-4,5-diaminocyclopent-2-enones from 2-furaldehyde and primary amines has been carried out.

Two new triply bridged Cu(II) compounds [Cu3(bpy)2(μ‐ClCH2COO)6] (1) and [Cu2(bpy)2(μ‐OH)(μ‐OH2)(μ‐ClCH2COO)](ClO4)2 (2) (where, bpy=2,2’‐bipyridine) have been synthesized and their magnetic properties have been measured and correlated with structure. Compound 1 is a novel centrosymmetric tricopper compound with only carboxylate bridges. The terminal Cu2+ ions have [5 + 1] coordination while the central ion has [4 + 2] coordination. The three centres are antiferromagnetically coupled, the exchange parameters for the neighbouring and distant pairs of Cu(II) atoms being 2 J=–28.6 cm–1 and 2 J'=–1.0 cm–1, respectively. In compound 2 three types bridging modes are observed, viz., hydroxo, aquo and carboxylato. The two Cu(II) centers are ferromagnetically coupled (2 J=73.8 cm–1) as previously observed for several di‐copper complexes with the same bridges. DFT calculations are in reasonable agreement with the magnetic exchange parameters for both dinuclear and trinuclear compounds.
