摘要

先前报道的Mn0-MgII键合杂双金属化合物[L†Mn-Mg (MesNacnac)] (L†=−N(Ar†)(SiPri3)， Ar†= C6H2{C(H)Ph2} 2pri -2,6,4;MesNacnac = [(MesNCMe)2CH]−;Mes = MesNacnac)在THF中溶解时形成加合物[L†Mn-Mg (THF)(MesNacnac)]。外来水被[L†Mn - mg (MesNacnac)]还原成氢氧化物桥接的杂双金属[L†Mn(μ-OH)2Mg(MesNacnac)]。在THF的存在下，Mn0-MgII键合的异金属氧化物使CO2发生还原性歧化，生成碳酸盐桥接物[{L†Mn(μ-CO3)Mg(THF) (MesNacnac)}2]。这三种新化合物已经进行了晶体学表征。

X-ray crystal structures of carbonate and hydroxide bridged MnII/MgII heterobimetallic complexes formed by reduction of CO2 or H2O by a Mn0–MgII bonded compound

Abstract The previously reported Mn0–MgII bonded heterobimetallic compound [L†Mn–Mg(MesNacnac)] (L† = −N(Ar†)(SiPri3), Ar† = C6H2{C(H)Ph2}2Pri-2,6,4; MesNacnac = [(MesNCMe)2CH]−; Mes = mesityl) forms an adduct complex, [L†Mn–Mg(THF)(MesNacnac)], when dissolved in THF. Adventitious water is shown to be reduced by [L†Mn–Mg(MesNacnac)] to give the hydroxide bridged heterobimetallic, [L†Mn(μ-OH)2Mg(MesNacnac)]. The Mn0–MgII bonded heterobimtallic reductively disproportionates CO2, affording the carbonate bridged species, [{L†Mn(μ-CO3)Mg(THF) (MesNacnac)}2], in the presence of THF. The three new compounds have been crystallographically characterized.

期刊介绍： This journal is committed to the publication of short communications, original research, and review articles within the field of main group metal and semi-metal chemistry, Main Group Metal Chemistry is an open-access, peer-reviewed journal that publishes in ongoing way. Papers addressing the theoretical, spectroscopic, mechanistic and synthetic aspects of inorganic, coordination and organometallic main group metal and semi-metal compounds, including zinc, cadmium and mercury are welcome. The journal also publishes studies relating to environmental aspects of these metals, their toxicology, release pathways and fate. Articles on the applications of main group metal chemistry, including in the fields of polymer chemistry, agriculture, electronics and catalysis, are also accepted.
