In the framework of resonating group method, we investigate the structure of the six-quark systems with strangeness s = -3 under the chiral SU(3) quark model. The calculations for single N Omega channel with spin S = 2 and the single Delta Omega channel with spin S = 3 are considered. The results show that both the systems can form loosely bound states where the forces induced by chiral fields play very important role.
