Six new uranium thiophosphates Cs5Na6[U(PS4)4](PS4) (1), Rb5Na3[U(PS4)4] (2), CsNa[U(PS4)2] (3), Cs1.67Na0.52I0.19[U(PS4)2] (4), Cs1.033Na1.343I0.376[U(PS4)2] (5), and Rb1.35Na0.93I0.28[U(PS4)2] (6) were obtained from halide flux reactions and characterized using single crystal X-ray diffraction. The structures of these compounds consist of a pseudo-tetrahedral uranium unit that in combination with a set of PS4 group coordination modes can result in an isolated [U(PS4)4]8– unit, a [U(PS4)2]2– chain, or a [U(PS4)2]2– slab. Optical and magnetic properties of 3 and 4 were collected. Both compounds exhibit paramagnetic behavior, and CsNa[U(PS4)2] (3) exhibits a magnetic transition at 200–225 K between two paramagnetic states that both have similar effective magnetic moments of 4.13 and 4.19 µB/F.U., and strong antiferromagnetic interactions with θ = -183 and -172 K, for the high- and low-temperature states, respectively.
