چکیده
The chains in complex [Mn(TPP)][Mn(TPP)(CN)2] (H2TPP = meso-tetra(4-phenyl)-porphyrin) demonstrate perfect linearity, and are well isolated with the nearest interchain Mn-Mn separation of 12.95 Å. Ferromagnetic coupling is present among adjacent Mn(III) ions, and single-chain magnet (SCM) behaviour is verified.

Spin canting, metamagnetism, and single-chain magnetic behaviour in a cyano-bridged homospin iron(II) compound.
Spin canting, antiferromagnetic ordering, metamagnetism and single-chain magnetism were verified in a cyano-bridged Fe(II) compound synthesized from the pentagonal bipyramidal Fe(II) starting material in the presence of excessive BF4(-) anions.
متن کاملSpectroelectrochemical evidence for communication within a laterally-bridged dimanganese(III) bis-porphyrin.
Electronic coupling between the porphyrin units of a laterally-bridged dimanganese(III) bis-porphyrin 2 is explored using electrochemistry, spectroelectrochemistry and resonance-Raman spectroscopy. It is found that strong electronic interactions between the manganese(III) ion and the porphyrin macrocycle enhance the perturbations experienced by these bis-porphyrin systems when compared to relat...
متن کاملDirected assembly of metal-cyanide cluster magnets.
The simple, well-understood coordination chemistry of the cyanide ligand is of significant utility in the design of new single-molecule magnets. Its preference for bridging two transition metals in a linear M'-CN-M geometry permits the use of multidentate blocking ligands in directing the assembly of specific molecular architectures. This approach has been employed in the synthesis of numerous ...
