Synthesis and Characterization of Pentanuclear Complexes Composed of Pairs of Macrocyclic Ni₂L and Zn₂L Complexes Linked by cis‐[PtCl₂(dppba)₂] and trans‐[RhCl(CO)(dppba)₂] [dppba = (4‐Diphenylphosphanyl)benzoate, L = Macrocyclic Ligand]

Synthesis and Characterisation of Luminescent [CrIII2L(μ‐carboxylato)]3+ Complexes with High‐Spin S=3 Ground States (L=N6S2 donor ligand)

“…The doubly deprotonated form, L 2− , is an effective dinucleating ligand that readily forms bioctahedral complexes of the type [M 2 L( μ ‐L′)] + with various first‐row transition metal ions (M=Mn 2+ , Fe 2+ , Co 2+ , Co 3+ , Ni 2+ , Figure 1 ). [38] Several co‐ligands such as L′=Cl − , OH − , [39] HS − , [40] and RCO 2 − ,[ 41 , 42 , 43 , 44 , 45 , 46 ] to name just a few, can be accommodated between the divalent metal ions. Complexes of this kind offer the opportunity to investigate intramolecular magnetic super‐exchange interaction as a function of the electronic configuration of the metal ions and the type of the coligand.…”

The Synthesis of Tetrazoles in Nanometer Aqueous Micelles at Room Temperature

“…We have also described related [{Ni 2 L} 2 (μ‐dppba) 2 M L′ 2 ] 2+ complexes, where a metallodicarboxylato ligand, namely [ M L′ 2 (dppba) 2 ] 2– [dppba = 4‐(diphenylphosphanyl)benzoate; M = Pd II , Rh I , Pt II ; L′ = Cl – , Br – , I – ], is encapsulated by the two {Ni 2 L} hemispheres 5. These compounds could be prepared in much the same way as those bearing the purely organic dicarboxylato ligands, i.e.…”
