Under hydrothermal conditions, two new 3D actinide–silver (An–Ag) heterometallic coordination polymers, namely, [Ag(UO2)2(µ2‐OH)(bpdc)2(H2O)2]n(1) and [Ag3Th6(µ3‐O)(µ3‐OH)(µ2‐OH)6(bpdc)6(NO3)6·H2O]n(2, H2bpdc = 2,2′‐bipyridine‐3,3′‐dicarboxylic acid), were assembled through a hard–soft recognition strategy. Compounds1and2were characterized by single‐crystal X‐ray diffraction, powder X‐ray diffraction, and infrared spectroscopy. Both compounds are constructed through the bridging of infinite polynuclear An–bpdc chiral helical chains by AgIcations. Compound2represents the first ThIV–AgIheterometallic coordination polymer. Furthermore, the thermal stability and luminescence properties of1were studied.
