Mukherjee, Shreya published the artcileA variety of new tri- and tetranuclear Mn-Ln and Fe-Ln (Ln = lanthanide) complexes, Application In Synthesis of 2212-32-0, the main research area is manganese gadolinium carboxylate heterometallic cluster preparation crystal structure; iron gadolinium carboxylate heterometallic cluster preparation crystal structure; magnetic property iron manganese gadolinium heterobimetallic cluster; transition metal lanthanide carboxylate heterometallic cluster preparation crystal structure.
The use of carboxylates in the synthesis of 3d/4f clusters, with or without a second organic ligand, has afforded tetranuclear M2Gd2 complexes (M = Fe or Mn), and two new trinuclear M2Gd (M = Fe or Mn) mol. compounds Only one of these, [Mn2Gd2O2(O2CBut)8(HO2CBut)4] (1), does not contain a multidentate chelate ligand. Two other similar tetranuclear clusters were synthesized from the use of triethanolamine (teaH3) and 1,1,1-tris(hydroxymethyl)ethane (thmeH3). [Mn2Gd2(OH)2(O2CPh)4(NO3)2(teaH)2] (2) has very similar structure with 1, bearing a defective incomplete double-cubane core bridged by μ3-O atoms, whereas in the core of [NHEt3]2[Fe2Gd2(O2CPh)4(thme)2(NO3)4] (3) the thme3- ligand caps the two incomplete cubane units, providing the triply-bridging alkoxides needed for bridging. Two new oxide-centered triangular clusters were synthesized bearing the Schiff-based chelate 2-{[2-(dimethylamino)ethyl]methylamino}ethanol (dmemH), [Fe2GdO(O2CBut)2(dmem)2(NO3)3] (4), and [Mn2GdO(O2CBut)2(dmem)2(NO3)3] (5). Magnetic susceptibility measurements and/or reduced magnetization studies established that complexes 1 and 3 have an S = 5 ground state, complex 2 has S = 4, and complexes 4 and 5 are S = 7/2 in their ground states. These complexes portray the feasibility of obtaining products bearing metal cores commonly found in homometallic clusters, even when these include metals with completely different coordination chem. and electronic structure, such as lanthanides.
