Keeping dysprosium in line: Trinuclear heterometallic M^II₂Dy^III complexes with M=Cd, Co and Cu

Zeitschrift für anorganische und allgemeine Chemie (2022)

Thomas Ruppert Sören Schlittenhardt Nithin Suryadevara Olaf Fuhr Christopher E. Anson

Abstract Four new heterometallic trinuclear essentially linear (“in‐line”) M II 2 Dy III complexes (M=Cd II ( 1 ), Co II ( 2 ), Cu II ( 3 , 4 ) were synthesised using the ligand 3,5‐di‐ tert ‐butylbenzoic acid (dtbbaH) in a MeCN : i PrOH ( 1–3 ) or in a MeOH : i PrOH : DMF ( 4 ) mixture. Single crystal structure analyses revealed the formation of [Cd 2 Dy(dtbba) 6 ( i PrOH) 2 (H 2 O) 2 NO 3 ] ⋅ i PrOH ( 1 ), [Co 2 Dy(dtbba) 6 ( i PrOH) 2 (H 2 O) 2 NO 3 ] ⋅ i PrOH ( 2 ), [Cu 2 Dy(dtbba) 6 (MeCN) 4 NO 3 ] ⋅ MeCN ( 3 ) and [Cu 2 Dy(dtbba) 6 ( i PrOH) 1.68 (DMF) 1.32 (H 2 O)NO 3 ] ⋅ 3 i PrOH ⋅ H 2 O ( 4 ). The M−Dy−M angles become more acute from ( 1 ) to ( 3 ) leading to decreased M⋅⋅M distances. The Dy III ions are 8‐coordinate with a distorted triangular dodecahedron geometry and a D 2d symmetry whereas the geometry of the 5‐coordinate terminal M II ions can best be described as either distorted vacant octahedra or as spherical square pyramids with a C 4v symmetry. Magnetic susceptibility measurements were performed on ( 1 ), ( 2 ) and ( 3 ) which allows a comparison of the effect of replacing highly anisotropic Co II with the quantum spin of Cu II . Both ( 2 ) and ( 3 ) show effects of ferromagnetic interactions at low temperatures.

Chiral Resolution of Spin‐Crossover Active Iron(II) [2x2] Grid Complexes

Chemistry - A European Journal (2021)

Nithin Suryadevara Ansgar Pausch Eufemio Moreno Pineda Asato Mizuno Jochen Bürck

Abstract Chiral magnetic materials are proposed for applications in second‐order non‐linear optics, magneto‐chiral dichroism, among others. Recently, we have reported a set of tetra‐nuclear Fe(II) grid complex conformers with general formula C/S‐[Fe 4 L 4 ] 8+ (L: 2,6‐bis(6‐(pyrazol‐1‐yl)pyridin‐2‐yl)‐1,5‐dihydrobenzo[1,2‐d : 4,5‐d′]diimidazole). In the grid complexes, isomerism emerges from tautomerism and conformational isomerism of the ligand L, and the S‐type grid complex is chiral, which originates from different non‐centrosymmetric spatial organization of the trans type ligand around the Fe(II) center. However, the selective preparation of an enantiomerically pure grid complex in a controlled manner is difficult due to spontaneous self‐assembly. To achieve the pre‐synthesis programmable resolution of Fe(II) grid complexes, we designed and synthesized two novel intrinsically chiral ligands by appending chiral moieties to the parent ligand. The complexation of these chiral ligands with Fe(II) salt resulted in the formation of enantiomerically pure Fe(II) grid complexes, as unambiguously elucidated by CD and XRD studies. The enantiomeric complexes exhibited similar gradual and half‐complete thermal and photo‐induced SCO characteristics. The good agreement between the experimentally obtained and calculated CD spectra further supports the enantiomeric purity of the complexes and even the magnetic studies. The chiral resolution of Fe(II)‐ [2×2] grid complexes reported in this study, for the first time, might enable the fabrication of magneto‐chiral molecular devices.
