A cyano-bridged single-chain magnet featuring alternate high- and low-spin manganese(iii) porphyrins†
Abstract
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.
