Aufbau Germylidin‐verbrückter Drei‐ und Vierkerncluster

Abstract: Die Umsetzung von Organogermaniumtrihalogeniden mit KCo(CO), liefert sowohl die Dreikerncluster RGeCo,(CO), (1, R = Me, Ph, tBu) als auch die neuen Vierkerncluster (RGe)2C04(CO),, (3, R = Ph, tBu). Die durch Insertion von GeI, in Metall-Metall-Bindungen entstehenden Zweikernkomplexe L,M -GeI, -ML, (4 -6, ML, = FeCp(CO),, Co(CO),, NiCpCO) setzen sich mit KCo(CO), zu den Clustern L,M -GeCo3(CO), (7 -9) um. Metallaustauschreaktionen liefern die Heterovierkerncluster (ZBuGe),Co,(CO),M'L, (10, 11, M'L, = MoCp(CO),,… Show more

“…The additional MeGeCo unit needed for l a is then supplied by [Co(GeMeH,)(CO),], as in equation (3). Heating the product mixture subsequently converted 3 into l a as in equation (2). Methylgermane may be converted even more directly into l a by thermolysis of the initial product, 6.…”

“…Relative intensities were 17,14,17,25,23,34,100,93,57,23,42,51,39 and 77% for n = 0 to 13 respectively. The much weaker series ( P -nCO -CH,)+ occurred with only l-lO% of these intensities apart from n = 3 and 2 (20) and n = 0 (73%). The only other significant ions were Ge,Co,+(71), MezGe,Co3+ ( 15), MeGe,Co,+(24), Ge,Co,+(27), MeGe,-C0,+(20), Ge,Co,+(23), Ge,Co+ ( 19), Me,Ge+(l9) and MeGe + (3 1 "/,).…”
