A F-bridged Mn(ii) molecular square

Abstract

We report on a tetranuclear Mn(II) complex possessing a F-bridged molecular square topology directed by 1,10-phenanthroline ligands.

Fluoride Bridges as Structure-Directing Motifs in 3d-4f Cluster Chemistry

“…It is noteworthy, that the cis configuration of the fluoride ligands in [CrF 2 (phen) 2 ] + does not suffice to introduce chelate binding toward the lanthanoid ions. A similar result has recently been observed for a homometallic tetranuclear manganese(II) cluster: [Mn II 4 F 4 (phen) 8 ](NO 3 ) 4 ·12H 2 O and parallels the tetra-nuclear structures with approximately linear fluoride bridges found for many metal pentafluorides. Thus, while many examples are known with doubly bridging hydroxide, oxide, and the heavier halides, fluoride clearly disfavors this structural motif.…”

“…The low-angle part of the powder diffraction also demonstrates the Dy-compound to contain a crystalline impurity. 14 and parallels the tetra-nuclear structures with approximately linear fluoride bridges found for many metal pentafluorides. Thus, while many examples are known with doubly bridging hydroxide, oxide, and the heavier halides, fluoride clearly disfavors this structural motif.…”

Effects of Catalyst Pore Structure and Acid Properties on the Dehydration of Glycerol

“…In recent years, the design and synthesis of metal‐organic coordination complexes are of continuous interest not only for their interesting molecular topologies1,2 but also for their potential applications in chemical engineering, chemistry, and materials science including gas storage, luminescent, conductive material, and DNA binding 3–7. Nitrogen ligands, particularly in the form of N‐heterocycles, have been widely used in the construction of coordination complexes 8,9.…”
