Abstract

The synthesis of [M(dimphen)(NCS)₂] (1; M = Fe^II), (2; M = Co^II), (3; M = Mn^II) and [Fe(dimphen)(NCSe)₂] (4), where dimphen = [1,2-bis(9-methyl-1,10-phenanthrolin-2-yl)ethane], are reported. The crystal packing structures of 1–3, show intermolecular π–π stacking and NCS⋯SCN interactions. The complex 1 shows ferromagnetic interaction, and the complex 2 displays single-molecular magnet behaviour.
