Preparation of a “twisted basket” Mn4N8 cluster: a two-hydrogen-atom reduced analogue of the Mn4N8 pinned butterfly

Abstract

Mn4(μ-NHPh)4(μ-PhNNPh-κ(2)N,N')2(py)4 () 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-κ(3)N,N')2(μ-PhNNPh-κ(2)N,N')(py)4 "pinned butterfly" cluster (), formally reduced by two hydrogen atoms. Cluster may be converted to by addition of N,N'-diphenylhydrazine as a two-electron reductant.

Computing stoichiometric molecular composition from crystal structures

“…For example, the COD 7115272 structure (Gau et al, 2014) belongs to the space group Table 1 Run times of the stoichiometric molecule reconstruction algorithms.…”

Hemicubane topological analogs of the oxygen-evolving complex of photosystem II mediating water-assisted propylene carbonate oxidation

“…However, most functional models [11][12][13][14][15][16][17][18][19][20] of the OEC do not have biomimetic topology, and most molecular topological mimics [21][22][23][24][25] do not show biomimetic chemistry, with some exceptions. [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43] Electrochemistry is an oft-employed tool for investigation of catalytic water oxidation by biomimetic systems. 13,26,34,43 An example particularly germane to this report is the oxidation of water to hydrogen peroxide by a manganese cluster from Agapie.…”
