By using the plot argument you should plot the first column of the data frame against the third column to show the "distances" between these points. Just by using the observations on the x-axis the red group is split up, but the values of the red group are still near to each other!
What version of R is this?

Not the clustering is the problem but your synthetic dataset. You're having a big overlap in classes...
