We perform a study of exclusive production ofD^+_sD^-_s, D^*+_sD^-_s, and D^*+_sD^*-_s final states in initial-state-radiation events from e^+ e^- annihilations at a center-of-mass energy near 10.58 GeV, to search for charmonium 1^-- states. The data sample corresponds to an integrated luminosity of 525 fb^-1 and was recorded by the BaBar experiment at the PEP-II storage ring. The D^+_sD^-_s, D^*+_sD^-_s, and D^*+_sD^*-_s mass spectra show evidence of the known ψ resonances. Limits are
