Abstract

The synthesis and characterization of two heterobimetallic complexes [K([18]crown-6){(η⁴-C₁₄H₁₀)Fe(μ-η⁴:η²-P₄)Ga(nacnac)}] (1) (C₁₄H₁₀ = anthracene) and [K(dme)₂{(η⁴-C₁₄H₁₀)Co(μ-η⁴:η²-P₄)Ga(nacnac)}] (2) with strongly reduced P₄ units is reported. Compounds 1 and 2 are prepared by reaction of the gallium(III) complex [(nacnac)Ga(η²-P₄)] (nacnac = CH[CMeN(2,6-iPr₂C₆H₃)]₂) with bis(anthracene)ferrate(1-) and -cobaltate(1-) salts. The molecular structures of 1 and 2 were determined by X-ray crystallography and feature a P₄ chain which binds to the transition metal atom via all four P atoms and to the gallium atom via the terminal P atoms. Multinuclear NMR studies on 2 suggest that the molecular structure is preserved in solution.

铁镓和钴镓四磷酸配合物。

报道了两种具有强还原P4单元的杂双金属配合物[K([18] -6){(η4-C14H10)Fe(μ-η4:η2-P4)Ga(nacnac)}] (1) (C14H10 =蒽)和[K(dme)2{(η4-C14H10)Co(μ-η4:η2-P4)Ga(nacnac)}](2)的合成和表征。化合物1和2是由镓(III)配合物[(nacnac)Ga(η - 2- p4)] (nacnac = CH[CMeN(2,6- ipr2c6h3)]2)与双(蒽)高铁酸盐(1-)和-钴酸盐(1-)反应制备的。1和2的分子结构由x射线晶体学确定，其特征是P4链通过所有四个P原子与过渡金属原子结合，并通过末端P原子与镓原子结合。对2的多核磁共振研究表明其分子结构在溶液中保持不变。

期刊介绍： ZAAC is an international scientific journal which publishes original papers on new relevant research results from all areas of inorganic chemistry, solid state chemistry, and co-ordination chemistry. The contributions reflect the latest findings in these research areas and serve the development of new materials, such as super-hard materials, electrical superconductors, or intermetallic compounds. Up-to-date physical methods for the characterization of new chemical compounds and materials are also described.
