Iron and cobalt complexes of tetramethylcyclam and D12-tetramethylcyclam were ozonized at low temperature and the samples subjected to analysis by cold electrospray mass spectrometry (cold ESI-MS; measured on a UHR-TOF Bruker Daltonik maXis plus instrument) and ultraviolet-visible spectroscopy (UV-Vis; measured on a Jasco V-760 instrument). Data is presented as x,y pairs of values in ASCII encoding and in CSV format. Additional experimental metadata is provided for each data subset in file readme.txt. All files can be read by any standard text or stream editor and imported into spreadsheet or plotting software for visualization.
