We present 8.4 GHz VLA A–configuration observations of 87 sources from the
mid–infrared–selected AGN sample of Rush et al. (1993). These 0.25 arcsec resolution
observations allow elongated radio structures tens of parsecs in size to be resolved and
enable radio components smaller than 3.5 arcsec to be isolated from diffuse galactic
disc emission. When combined with previous data, matched radio observations covering ninety percent of the sample have been collected and these represent the largest
sub–arcsecond–resolution radio imaging survey of a homogeneously–selected sample
of Seyfert galaxies to date. We use our observations to identify 5 radio–loud AGN in the sample. The nature of the radio emission from Seyfert nuclei will be discussed in subsequent papers.
