Abstract
We use a constituent model to analyze the stability of pentaquark configurations with a heavy antiquark or , and four light quarks , or . The interplay between chromoelectric and chromomagnetic effects is not favorable, and, as a consequence, no bound state is found below the lowest dissociation threshold.
