Spin crossover in phosphorus- and arsenic-bridged cyclopentadienyl-manganese(II) dimers.

چکیده
Manganocene reacts with LiE(SiMe(3))(2) (E = P or As) to give [(η(5)-Cp)Mn{μ-E(SiMe(3))(2)}](2), where E = P (1) or As (2). The temperature dependence of the magnetic susceptibility in 1 and 2 is due to antiferromagnetic exchange and to spin-crossover (SCO). Compound 2 shows two-step SCO with hysteresis, involving high-spin (S = 5/2) and intermediate-spin S = (3/2) Mn(II).

The high-spin/low-spin bistability of spin-crossover (SCO) transition metal complexes is a fascinating property that attracts considerable interest because of its potential applications in molecular switches. The largest class of SCO compounds comprises monometallic, octahedral iron(II) complexes with six N-donor ligands, whose bistability involves interconversions of the high-spin (t2g) 4 (eg)...
متن کاملExchange-coupled oxygen- and sulfur-bridged cyclopentadienyl-manganese(II) cages.
The trimetallic complex [{CpMn(μ-OSiPh3)2}2Mn] (1) and the heterocubane [CpMn(μ3-SSiPh3)]4 (2) are formed by deprotonation of Ph3SiQH (Q = O, S) by manganocene, or by transmetallation of manganocene by Ph3SiQLi. The Mn(II) centres in 1 and 2 are antiferromagnetically coupled, with J = −4.4 and −3.0 cm(−1) in 1 and 2, respectively (−2J formalism).
متن کاملBioinspired manganese(II) complexes with a clickable ligand for immobilisation on a solid support.
Clickable ligands like N,N'-bis((pyridin-2-yl)methyl)prop-2-yn-1-amine (L(1)) and N-((1-methyl-1H-imidazol-2-yl)methyl)-N-(pyridin-2-ylmethyl)prop-2-yn-1-amine (L(2)) have been used to synthesise a series of manganese(ii) complexes for grafting onto appropriate solid supports. These ligands mimic the 2-His-1-carboxylate facial chelation present in the active site of the manganese-dependent diox...
متن کاملTwo-dimensional Manganese(II) Coordination Polymer Complex Containing Aqua, Diethyl Phosphate and Chloride Ligands: Synthesis, Spectroscopic Characterization, Thermal Analyses, and Crystal Structure
A new two-dimensional manganese(II) coordination polymer, [Mn(μ-DEP)(μ-Cl)(H2O)2]n (1) (DEP is diethyl phosphate), was prepared from the reaction of MnCl2.4H2O and TEP (TEP is triethyl phosphate) ligand in mixture of H2O/CH3OH (1:10) at 40 °C. Suitable crystals of this complex for crystal structure determination were obtained by slow evaporation of the produced colorless solution at room temper...
متن کاملRedox Interaction between Binuclear Mn2(III/IV) Complexes and Binuclear Mn2(II/II) Complexes
A dominant feature of the inorganic chemistry of manganese is the variety of complexes that can be made with different oxidation levels ( + 11+ IV) of the manganese, and living systems have utilized this property in that manganese-containing en zymes are involved in many diverse redox func tions [1]. The biological function that has generat ed most interest is the photosynthetic oxygen evolv...
