The catalytic activity of metal‐oxide materials can be tuned by adjusting the local composition of the metal centers, as demonstrated by a gas‐phase example. [Al 2 VO 5 ] + selectively breaks only one C−H bond with concomitant generation of a methyl group, either chemisorbed on an Al center or liberated at room temperature. By replacing one Al atom of [Al 2 VO 5 ] + with a V=O unit, the cluster [AlV 2 O 6 ] + gains a higher oxidizing ability such that it converts methane to formaldehyde.
