2,2′-Dipyridylamino-based ligands with substituted alkyl chain groups and their mononuclear-M(ii) spin crossover complexes

Abstract

Four new alkyl chain appended dipyridylamino-substituted-s-triazine ligands have been incorporated into seven new, mononuclear MII compounds of type [MII(NCX)2(L)2] (where NCX = NCS or NCSe, L = dipyridylamino-substituted-s-triazine-based ligand and MII = Fe or Co). These complexes have been structurally and magnetically characterised. The magnetic consequence of varying the alkyl chain length has been investigated in terms of intermolecular interactions and crystallographic packing arrangements. For selected complexes photomagnetic LIESST (Light-Induced Excited Spin State Trapping) measurements have been performed revealing reversible photo-induced spin-state switching.
