Abstract

A series of new Pd–Mn bimetallic acetate and pivalate complexes were synthesized and structurally characterized. The starting [Pd(OOCMe)₄Mn] complex reacts with N‑donor ligands such as 1,10-phenanthroline (phen) to give [Pd(OOCMe)₄Mn(phen)]⋅MeCN (I) (CCDC no. 2217716). The replacement of acetate bridges in the heterometallic Pd–Mn carboxylate complexes with pivalate bridges was investigated. It was shown that complete replacement of all acetate bridges with pivalate ones can occur both in heterometallic complex I, which contains a ligand coordinated to the second metal atom, to give the compound [Pd(Piv)₄Mn(phen)]⋅C₆H₆ (II) (CCDC no. 2217717), structurally related to the initial acetate complex, and in the acetate complex [Pd(OOCMe)₄Mn]. The heterometallic co-crystallized pivalate [Pd(Piv)₄Mn⋅2HPiv] (III) (CCDC no. 2217718) formed in the latter case can react with 5-nitro-1,10-phenanthroline to give the complex [Pd(Piv)₄Mn(Nphen)] (IV) (CCDC no. 2217719).

[Pd(OOCMe)4Mn]与 1,10-菲罗啉和特戊酸反应中的化学变化

摘要合成了一系列新的 Pd-Mn 双金属醋酸盐和新戊酸盐配合物，并对其进行了结构表征。起始[Pd(OOCMe)4Mn]配合物与 1,10-菲罗啉（phen）等 N-供体配体反应生成[Pd(OOCMe)4Mn(phen)]⋅MeCN (I)（CCDC 编号：2217716）。研究了用特戊酸桥取代 Pd-Mn 羧酸异金属配合物中的醋酸桥的问题。结果表明，在杂金属络合物 I（该络合物含有与第二个金属原子配位的配体）和醋酸盐络合物 [Pd(OOCMe)4Mn]中，所有醋酸盐桥都可以被新戊酸桥完全取代，从而得到化合物 [Pd(Piv)4Mn(phen)]⋅C6H6 (II)（CCDC 编号 2217717），该化合物在结构上与最初的醋酸盐络合物有关。在后一种情况下形成的异金属共结晶新戊酸盐[Pd(Piv)4Mn⋅2HPiv]（III）（CCDC 编号：2217718）可与 5-硝基-1,10-菲罗啉反应，生成络合物[Pd(Piv)4Mn(Nphen)]（IV）（CCDC 编号：2217719）。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
