We have studied the correlation between 2357 Chandra X-ray point sources identified by Muno et al. (2003) in a 40 × 40 parsec field and ∼20,000 infrared sources we observed in the corresponding subset of our 2 × 1.5 degree Spitzer/IRAC Galactic Center Survey at 3.6-8.0 μm (see Stolovy et al.; this conference), using various spatial and brightness thresholds. The correlation was determined for source separations of less than 0.5, 1.0 or 2.0 arcsec. No significant correlation was found between the X-ray and infrared point sources on these scales. Only one compact infrared source, IRS 13, can be identiffed with any of the dozen prominent X-ray emission features in the 3 × 3 parsec region centered on Sgr A*, and the diffuse X-ray and infrared emission around Sgr A* seems to be anti-correlated on a few-arcsecond scale. We compare our results with previous identifications of near infrared companions to Chandra X-ray sources.
