  On the Road to a Termolecular Complex with Acetone:  A Heterometallic Supramolecular Network {[Rh₂(O₂CCF₃)₄]·μ₂-OCMe₂·[Cu₄(O₂CCF₃)₄]}

  摘要：

  A novel heterometallic supramolecular network {[Rh-2(O2CCF3)(4)].mu(2)-OCMe2.[Cu-4(O2CCF3)(4)]}(2)(infinity) has been prepared by codeposition of the volatile mono(acetone) adduct [Rh-2(O2CCF3)(4).eta(1)-OCMe2](2) and copper(I) trifluoroacetate, [Cu-4(O2CCF3)(4)]. The product is of interest from the viewpoints of gas-phase supramolecular synthesis and a rare bridging coordination mode of acetone. It has been fully characterized by IR and NMR spectroscopy, elemental analysis, and X-ray diffraction. An X-ray structure revealed a layered 2D arrangement of the heterometallic {[Rh-2(O2CCF3)(4)].mu(2)-OCMe2.[Cu-4(O2CCF3)(4)]} units built by axial intermolecular interactions of the open electrophilic Rh(II) and Cu(I) centers and O-atoms of neighboring carboxylate groups. The coordination of the acetone molecules within the {[Rh-2(O2CCF3)(4)].mu(2)-OCMe2.[Cu-4(O2CCF3)(4)]} unit is asymmetric with the Rh-O and Cu-O distances being 2.2173(15) and 2.7197(17) Angstrom, respectively. This work shows the potential of gas-phase deposition that may provide additional possibilities in supramolecular synthesis by utilizing intermolecular interactions and coordination bonds in a new way compared with conventional solution chemistry.

  diyne. This has demonstrated the donor ability of the diiodobutadiyne that was previously known to act as a π-acceptor through the Lewis acidic iodine atoms. This work has expanded the temperature limits of the solvent-free synthesis strategy for potential study of thermally unstable species.

  在升华-沉积反应中，使用丙酮单加合物[Rh 2（O 2 CCF 3）4 ·（OCMe 2）]代替未连接的四（三氟乙酸）二氢吡啶鎓（II），可以研究热敏性1， 4-二碘-1,3-丁二炔。一种新的混合配体有机金属化合物，[Rh 2（O 2 CCF 3）4 ·（OCMe 2）] 2 ·（C 4 I 2），已经以晶体形式分离出来，并通过X射线衍射研究表明其具有η 2（1,2）：η 2二炔的（3,4）-桥接模式。这证明了以前已知通过路易斯酸性碘原子充当π-受体的二碘丁二炔的供体能力。这项工作扩大了无溶剂合成策略的温度范围，可用于热不稳定物质的潜在研究。
