在研究Co(acac)_3和pph_3和Al(C_2H_5)_3在乙醚溶液中与CO_2反应时,我们得到了两种晶体,其一为深红色,组成是CoH(CO)(pph_3)_3·(C_2H_5)_2O;其二为橙红色,组成为CoH(CO)(pph3)_3。它们在空气中很快分解,但晶体Ⅰ较晶体Ⅱ稍许稳定。
In the study of Co (acac) _3 and pph_3 and Al (C_2H_5) _3 reacted with CO_2 in ether solution, we got two kinds of crystals, one of which is dark red with the composition of CoH (CO) (pph_3) _3 · (C_2H_5 ) _2O; the other is orange-red with the composition of CoH (CO) (pph3) _3. They quickly decompose in the air, but Crystal I is slightly more stable than Crystal II.
