We present a catalog of 9017 X-ray sources identified in Chandra observationsof a 2 by 0.8 degree field around the Galactic center. We increase the numberof known X-ray sources in the region by a factor of 2.5. The catalogincorporates all of the ACIS-I observations as of 2007 August, which total 2.25Msec of exposure. At the distance to the Galactic center (8 kpc), we aresensitive to sources with luminosities >4e32 erg/s (0.5-8.0 keV; 90%confidence) over an area of one square degree, and up to an order of magnitudemore sensitive in the deepest exposure (1.0 Msec) around Sgr A*. The positionsof 60% of our sources are accurate to <1" (95% confidence), and 20% havepositions accurate to <0.5". We search for variable sources, and find that 3%exhibit flux variations within an observation, 10% exhibit variations fromobservation-to-observation. We also find one source, CXOUGC J174622.7-285218,with a periodic 1745 s signal (1.4% chance probability), which is probably amagnetically-accreting cataclysmic variable. We compare the spatialdistribution of X-ray sources to a model for the stellar distribution, and find2.8 sigma evidence for excesses in the numbers of X-ray sources in the regionof recent star formation encompassed by the Arches, Quintuplet, and Galacticcenter star clusters. These excess sources are also seen in the luminositydistribution of the X-ray sources, which is flatter near the Arches andQuintuplet than elsewhere in the field. These excess point sources, along witha similar longitudinal asymmetry in the distribution of diffuse iron emissionthat has been reported by other authors, probably have their origin in theyoung stars that are prominent at l~0.1 degree.
