通过Rh-2（O2 CCF 3）（4）和Mo（CO）（6）在真空密封管中的反应，该真空密封管置于存在热梯度的热环境中（125-120 ℃）时，我们得到了一种化合物，其中一个Rh-2（O2 CCF 3）（4）单元夹在两个Rh-2（O2 CCF 3）（2）（CO）（4）单元之间，得到六个铑原子的基本线性排列，Rh-Rh距离为2.960（1）、2.790（1）和2.412（1）埃。然后，这些六个铑原子的阵列连接成无限的链，这些链在晶体中平行，Rh与Rh的接触为3.062（1）埃。晶体是明显的二色性和相对空气稳定。(C)2000 Elsevier Science S.A.

By reaction of Rh-2(O2CCF3)(4) and Mo(CO)(6) in an evacuated sealed tube placed in a thermal environment where there is a thermal gradient (125-120 degrees C), we have obtained a compound in which one Rh-2(O2CCF3)(4) unit is sandwiched between two Rh-2(O2CCF3)(2)(CO)(4) units, to give an essentially linear array of six rhodium atoms, with Rh-Rh distances of 2.960(1), 2.790(1) and 2.412(1) Angstrom. These arrays of six rhodium atoms are then linked into infinite chains which lie parallel in the crystal, with Rh to Rh contacts of 3.062(1) Angstrom. The crystals are markedly dichroic and relatively air stable. (C) 2000 Elsevier Science S.A. All rights reserved.
