Magnetic properties of pentacoordinate complexes of the type [Co(bzimpy)X 2 ], X = Cl and Br, were investigated in DC and AC modes. The DC data shows sizeable zero‐field splitting for these complexes. The AC susceptibility data confirms slow magnetic relaxation at the applied DC field with two relaxation channels. The low‐frequency relaxation time is as slow as τ LF ≈ 0.1–0.3 s for the Cl and Br complexes at T = 1.9 K.
