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] 在与 1,10-菲咯啉和新戊酸反应中的化学转化

摘要

合成了一系列新型钯-锰双金属乙酸盐和新戊酸盐络合物并进行了结构表征。起始的 [Pd(OOCMe)₄Mn] 配合物与 N 供体配体（例如 1,10-菲咯啉 (phen)）反应，生成 [Pd( OOCMe)₄Mn(phen)]⋅MeCN (I) (中央结算公司编号：2217716）。研究了用新戊酸桥取代异金属钯-锰羧酸盐配合物中的乙酸酯桥。结果表明，在异金属配合物 I 中都可以发生所有乙酸酯桥被新戊酸酯桥完全取代的情况，该配合物包含与第二个金属原子配位的配体，得到化合物 [Pd(Piv)₄Mn(phen)]⋅C_{6< a i=12>H6} (II)（中央结算公司编号：2217717） ），结构上与初始乙酸盐络合物相关，并且在乙酸盐络合物 [Pd(OOCMe)₄Mn] 中。异金属共晶新戊酸盐 [Pd(Piv)₄Mn⋅2HPiv] (III<后一种情况形成的 a i=22>) (CCDC no. 2217718) 可以与 5-硝基-1,10-菲咯啉反应生成络合物 [Pd(Piv)₄)（CCDC 编号 2217719）。IVMn(Nphen)] (
