Radiative decays of the $\psip$ into $\gamma K\bar{K}\pi$ and $\gamma\eta\pipi$ final states are studied using 14 million $\psip$ events collected with the BESII detector. Branching fractions or upper limits on the branching fractions of $\psip$ and $\xcj$ decays are reported. No significant signal for $\etafl/\etafh$ is observed in the $K\bar{K}\pi$ or $\eta\pipi$ mass spectra, and upper limits on the branching fractions of $\psip\rar\gamma\etaf$, $\etaf\rar K\bar{K}\pi$ and $\eta\pipi$ are determined.
