Title: A novel nonanuclear CuII carboxylate-bridged cluster aggregate with an S= 7/2 ground spin state Author:Murugesu, Muralee; King, Philippa; Clérac, Rodolphe; Anson, Christopher E; Powell, Annie K Description:
The Cu(II) aggregate in [Cu(9)(cpida)(6)(MeOH)(6)].6(MeOH)[H(3)cpida = 2-(carboxyphenyl)iminodiacetic acid] is made up of two weakly ferromagnetically coupled carboxylate-bridged Cu(4) units that are antiferromagnetically linked through a central Cu(II) to give a Cu(9) core with an S= 7/2 spin ground state.

Title: Ab initio study of the magnetic exchange coupling constants of a structural model CaMn(3)(III)Mn(II) of the oxygen evolving center in photosystem II Author:Fliegl, Heike; Fink, Karin; Klopper, Wim; Anson, Christopher E; Powell, Annie K; Clérac, Rodolphe Subject:Magnetics ; Models, Molecular ; Quantum Theory ; Manganese -- Chemistry ; Oxygen -- Chemistry ; Photosystem II Protein Complex -- Chemistry Description:
A new structural model for the oxygen evolving center in photosystem II was recently synthesized and characterized by Hewitt et al. (Chem. Commun., 2006, 2650). A simplified Heisenberg model Hamiltonian with only two independent constants was applied to extract the magnetic spin-coupling constants J(ij) of the mixed valent Mn(4) system. In the present study, all six possible coupling constants are calculated by ab initio methods in order to obtain a detailed understanding of the magnetic behavior of the system. The broken symmetry approach of Noodleman is applied using density functional theory (DFT). Two different approaches are compared. On the one hand, the coupling constants are obtained from calculations on eight different determinants which describe the high-spin state as well as different broken-symmetry states of the tetranuclear cluster. On the other hand, a pair approach that permits a direct calculation of the individual coupling constants is used. For the pair approach, the...

Title: Tridecanuclear [MnIII 5 LnIII 8 ] Complexes Derived from N-tButyl-diethanolamine: Synthesis, Structures, and Magnetic Properties Author:M. Ako, Ayuk; Mereacre, Valeriu; Clérac, Rodolphe; J. Hewitt, Ian; Lan, Yanhua; Buth, Gernot; E. Anson, Christopher; K. Powell, Annie Subject:Chemical Sciences ; Coordination Chemistry ; Synthesis ; Magnetic Properties ; Structures ; Chemistry Description:
The synthesis, structures and magnetic properties of a family of heterometallic [MnIII 5 LnIII 8 (μ3-OH)12(L2)4(piv)12- (NO3)4(OAc)4]- (Ln = Pr, 2; Nd, 3; Sm, 4; Gd, 5; Tb, 6) aggregates are reported. The complexes were obtained from the direct reaction of N-tbutyldiethanolamine (H2L2) with Mn(OAc)2 3 4H2O and Ln(NO3)3 3 6H2O in the presence of pivalic acid (pivH) in MeCN under ambient conditions. Compounds 2-6 are isomorphous and crystallize in the monoclinic space group P21/n with four molecules in the unit cell. The complexes have a centrosymmetric tridecanuclear anionic core consisting of two distorted inner heterometallic [MnIIILnIII 3 (μ3-OH)4]8+ cubane subunits sharing a common Mn vertex flanked by four edge-sharing heterometallic [MnIIILnIII 2 (μ3-OH)4]5+ defect cubane units. Complexes 2-6 are the first high-nuclearity 3d-4f aggregates reported to date using tBu-deaH2 as ligand. These compounds show no evidence of slow relaxation behavior above 1.8 K, which appears...

Title: A Mn18Dy SMM resulting from the targeted replacement of the central MnII in the S = 83/2 Mn19-aggregate with DyIII Author:Ako, Ayuk M; Mereacre, Valeriu; Clérac, Rodolphe; Wernsdorfer, Wolfgang; Hewitt, Ian J; Anson, Christopher E; Powell, Annie K Subject:Chemical Sciences/Material Chemistry; Description:
Anisotropy can be introduced into the [Mn(19)]-aggregate, which currently has the highest known spin ground state of S = 83/2, by the targeted replacement of the central Mn(II) cation with Dy(III) leading to a [Mn(18)Dy] complex with the same core topology showing slow relaxation of the magnetisation.
