o2no2nx
o2no2nx is a label encountered in some computational chemistry datasets and speculative literature to refer to a hypothetical nitrogen-oxide–containing molecule. It is not a recognized chemical name or formula in standard databases, and there is no verified experimental specimen associated with it.
The notation appears to concatenate fragments such as O2, NO2, and NX, where X represents a variable
In practice, o2no2nx is used mainly as a placeholder in reaction networks, machine learning training sets, or
