NewNew Method for Preparation of Nitrido¹⁸⁸Re Complexes

188ReNint2+ was obained easily in high yield(>95%) by using SDH（succinic dihydrazide） as a donor of nitride atom（N3-）,SnCl2•2H2O as a reducing agent and oxalic as an accelerant. Furthermore, a new compound 188ReN-NEPTDD, which was prepared with the radiochemical purity (RCP) over 90%.The compoud was highly stable.
