We present the first interferometric molecular line and dust emission mapsfor the Galactic Center (GC) cloud G0.253+0.016, observed using the CombinedArray for Research in Millimeter--wave Astronomy (CARMA) and the SubmillimeterArray (SMA). This cloud is very dense, and concentrates a mass exceeding theOrion Molecular Cloud Complex (2x10^5 M_sun) into a radius of only 3pc, but itis essentially starless. G0.253+0.016 therefore violates "star formation laws"presently used to explain trends in galactic and extragalactic star formationby a factor ~45. Our observations show a lack of dense cores of significantmass and density, thus explaining the low star formation activity. Instead,cores with low densities and line widths 1km/s---probably the narrowest linesreported for the GC region to date---are found. Evolution over several 10^5 yris needed before more massive cores, and possibly an Arches--like stellarcluster, could form. Given the disruptive dynamics of the GC region, and thepotentially unbound nature of G0.253+0.016, it is not clear that this evolutionwill happen.
