Summary: | Unlike CO, which is common in coordination chemistry and organometallic chemistry, little is known about SiO or GeO compounds. Here we report a Ge6O– cluster featuring a GeO triple bond. The structural and chemical bonding properties of Ge6O–/0 are investigated using anion photoelectron spectroscopy and theoretical calculations. Two nearly degenerate isomers have been found for Ge6O–. The lowest-energy structure (6A) can be viewed as an O atom bonding with a tetragonal bipyramidal Ge6. The second one (6B) can be considered as an O atom interacting with a capped trigonal bipyramidal Ge6. Chemical bonding analyses reveal that Ge6O– (6A) can be viewed as a GeO unit interacting with a σ antiaromatic C 2v symmetric tetragonal pyramidal Ge5 3– moiety. Comparisons of the chemical bonding in Ge6O– (6A) with that in Ge5CO– and Ge5MnO– indicate the similar behavior of GeO to CO and MnO in its bonding to the Ge5 3– and Ge5 4– moieties. |
