Mn4(μ-NHPh)4(μ-PhNNPh-κ2N,N′)2(py)4 (3) is synthesized via self assembly from dimeric Mn2(μ-NHPh)2(NR2)2 and PhNHNHPh (R = SiMe3). This cluster represents the N–N cleaved version of the previously-reported Mn4(μ-NHPh)2(μ3-PhNNPh-κ3N,N′)2(μ-PhNNPh-κ2N,N′)(py)4 “pinned butterfly” cluster (2), formally reduced by two hydrogen atoms. Cluster 2 may be converted to 3 by addition of N,N′-diphenylhydrazine as a two-electron reductant.
