  Synthesis and characterization of manganese(I) and rhenium(I) based M2L2- and M2(µ-Br)2L-type diethyleneglycol decorated ester functionalized metallacycles

  摘要：

  M2L2-type metallacycles [M(CO)(3)Br(mu-pcadgd)](2) (1, M = Mn; 2, M = Re) were prepared by the reaction of equimolar amounts of M(CO)(5)Br and 4-pyridinecarboxylic acid diethyleneglycol diester (L = pcadgd). On the other hand, polyether spacer containing bromido-bridged M-2(mu-Br)(2)L-type metallacycles [M-2(CO)(6)(mu-Br)(2)(mu-pcadgd)] (3, M = Mn; 4, M = Re) were obtained by treating two equivalents of M(CO)(5)Br with one equivalent of 4-pyridinecarboxylic acid diethyleneglycol diester (pcadgd). Compounds 1-4 were characterized using elemental analyses, NMR, IR and UV-Vis absorption spectroscopic techniques. Formation of 1-4 was ascertained by ESI-mass spectrometry, while the structural elucidation of bromido-bridged compound 3 was carried out by single-crystal X-ray diffraction analysis. This research work comprises the first Mn(I)-based polyether spacer containing dinuclear metallacycles with/without a bromido-bridge, along with their Re counterparts. The metallacycles 1-4 were obtained in a single-step directly from M(CO)(5)Br via a two precursor self-assembly. (C) 2017 Elsevier B.V. All rights reserved.
