  We investigate the symmetry property and the stability of dibaryons
containing two strange quarks and one heavy flavor with $I=\frac{1}{2}$. We
construct the wave function of the dibaryon in two ways. First, we directly
construct the color and spin state of the dibaryon starting from the four
possible SU(3) flavor state. Second, we consider the states composed of five
light quarks, and then construct the wave function of the dibaryon by adding
one heavy quark. The stability of the dibaryon against the strong decay into
two baryons is discussed by using variational method in a constituent quark
model with confining and hyperfine potential. We find that for all
configurations with S=0,1,2, the ground states of the dibaryons are the sum of
two baryons, and there are no compact bound state that is stable against the
strong decay.
