A new tetranuclear manganese complex [Mn 2 II Mn 2 III (bhmcpH) 2 (hmp) 4 Cl 2 (MeOH) 2 ] ( 1 ) [bhmcpH 3 = 2, 6‐bis(hydroxymethyl)‐4‐chlorophenol, hmpH = 2‐(hydroxymethyl)pyridine] was synthesized and characterized. X‐ray diffraction analyses reveal that complex 1 crystallizes in the monoclinic space group P 2 1 / c . It has a mixed‐valence tetranuclear dicubane unit, which comprises two Mn II and two Mn III ions. The temperature dependence of the magnetic susceptibilities of 1 indicates ferromagnetic interactions between the manganese ions.
