  Digermylene Oxide Stabilized Group 11 Metal Iodide Complexes

  摘要：

  Use of a substituted digermylene oxide as a ligand has been demonstrated through the isolation of a series of group 11 metal (I) iodide complexes. Accordingly, the reactions of digermylene oxide [{(i-Bu)(2)ATIGe}(2)O] (ATI = aminotroponiminate) (1) with CuI under different conditions afforded [({(i-Bu)(2)ATIGe}(2)O)(2)(Cu4I4)] (2) with a Cu4I4 octahedral core, [({(i-Bu)(2)ATIGe}(2)O)(2)(Cu3I3)] (3) with a Cu3I3 core, and [{(i-Bu)(2)ATIGe}(2)O(Cu2I2)(C5H5N)(2)] (4) with a butterfly-type Cu2I2 core. The reactions of compound 1 with AgI and AuI produced [({(i-Bu)(2)ATIGe}(2)O)(2)(Ag4I4)] (5) with a Ag4I4 octahedral core and [{(i-Bu)(2)ATIGe}(2)O(Au2I2)] (6) with a Au2I2 core, respectively. The presence of metallophilic interactions in these compounds is shown through the single-crystal X-ray diffraction and atom-in-molecule (AIM) studies. Preliminary photophysical studies on compound 6 are also carried out.

  Digermylene Oxide Complexes: Facile Synthesis and Reactivity

  摘要：

  A simple heating of aminotroponiminate (ATI) ligand stabilized germylene monochlorides [(R)(2)ATIGeCl] (R = t-Bu 1, i-Bu 2) with an excess of potassium hydroxide in toluene resulted in the first ATI ligand stabilized digermylene oxides [{(R)(2)ATIGe}(2)O] (R = t-Bu 3, i-Bu 4), respectively. Reaction of compound 3 with elemental sulfur and selenium gave the first germaacid anhydride complexes [{(t-Bu)(2)ATIGe(E)}(2)O] (E = S 5, Se 6) with (S)Ge-O-Ge(S) and (Se)Ge-O-Ge(Se) moieties, respectively. The digermylene oxide complexes 3 and 4 and germaacid anhydride complexes 5 and 6 were characterized by multinuclear NMR spectroscopy and single-crystal X-ray diffraction analysis. In its Se-77 NMR spectrum, compound 6 showed a resonance at -78.9 ppm. The Ge-O-Ge bond angles in compounds 5 and 6 are 178.66(2)degrees and 179.81(2)degrees, respectively. To understand further the bonding features, DFT calculations followed by MO, AIM, and NBO analysis were carried out on compounds 3, 5, and 6. The computed Wiberg bond indices of Ge-O bonds are slightly less than 0.5 in all the aforementioned compounds, and the same for the Ge=E bonds in compounds 5 and 6 are close to 1.4.

  The stability of ligand-stabilized carboxylic acid derivatives (such as esters, amides, anhydrides, and acid halides) with terminal Ge=Te bonds is highly questionable as there is no report on such compounds. Nevertheless, we are able to isolate germatelluroester [LGe(Te)Ot-Bu] (4), germatelluroamide [LGe(Te)N(SiMe3)(2)] (5), and germatelluroacid anhydride [LGe(Te)OGe(Te)L] (6) complexes (L = aminotroponiminate (ATI)) as stable species. Consequently, the synthetic details, structural characterization, and UV-vis spectroscopic and theoretical studies on them are reported for the first time.
