- Abstract: The complexes OCBeCO3 and COBeCO3 have been isolated in a low‐temperature neon matrix. The more stable isomer OCBeCO3 has a very high CO stretching mode of 2263 cm −1, which is blue‐shifted by 122 cm −1 with respect to free CO and 79 cm −1 higher than in OCBeO. Bonding analysis of the complexes shows that OCBeO has a stronger OCBeY bond than OCBeCO3 because it encounters stronger π backdonation. The isomers COBeCO3 and COBeO exhibit red‐shifted CO stretching modes with respect to free CO. The inverse change of CO stretching frequency in OCBeY and COBeY is explained with the reversed polarization of the σ and π bonds in CO. Abstract : Der Carbonylkomplex OC→BeCO3 wurde in einer Neon‐Matrix isoliert. Die C‐O‐Streckschwingungsfrequenz zeigt gegenüber freiem CO eine starke Blauverschiebung. Diese ist deutlich höher als in OC→BeO, obwohl die Donor‐Akzeptor‐Bindung deutlich schwächer ist. Dies wird mithilfe einer quantenchemischen Bindungsanalyse erklärt, die auch die Rotverschiebung bei den Isomeren OC→BeCO3 und OC→BeO erklärt.
