  Abstract In contrast to the “Pr-issue” that neither PrBa₂Cu₃O₇ (Pr123) nor PrBa₂Cu₄O₈ (Pr124) shows superconductivity (SC), we have observed 100%-fraction of SC in an oxygen-reduced Pr₂Ba₄Cu₇O_15−δ (Pr247) which has a hybrid structure that Pr247 = Pr123 + Pr124. It is found that Cu nuclear-spin signals from the CuO₂ planes observed at 300 K are completely wiped out at 2 K. Instead, the plane signals at 2 K are observed at higher frequencies. This indicates that, despite the bulk SC, the CuO₂ planes in Pr247 are found to be in an insulating and antiferromagnetically ordered state.
