The novel mononuclear Co(II) complex cis-[CoII(dmphen)2(NCS)2]·0.25EtOH (1) (dmphen = 2,9-dimethyl-1,10 phenanthroline) features a highly rhombically distorted octahedral environment that is responsible for the strong positive axial and rhombic magnetic anisotropy of the high-spin CoII ion (D = +98 cm−1 and E = +8.4 cm−1). Slow magnetic relaxation effects were observed for 1 in the presence of a dc magnetic field, constituting the first example of field-induced single-molecule magnet behavior in a mononuclear six-coordinate Co(II) complex with a transverse anisotropy energy barrier.
