The complex 1 can be regarded as a kind of “inorganic sandwich compound” without metal–metal bonds: It contains an Mn II atom sandwiched between two relatively flat [Mn 4 III O 2 ] moieties. 1 is obtained in the form of black crystals on treatment of [Mn 3 O(O 2 CPh) 6 (py) 2 (H 2 O)] in acetonitrile with solid salicylic acid. Noteworthy is the high yield of ca. 40%. The magnetic susceptibility of 1 points to strong coupling of the lone electrons.
