N2 - Single crystals of Cs2(UO2)(NO3)Cl 3 were prepared by a hydrothermal method at 205 °C. The crystal structure has been solved by Direct Methods: monoclinic, P21/n, a = 10.3748(13), b = 9.4683(13), c = 12.5535(16) Å β = 110.280(2)°, V = 1156.7(3) Å3, R1 = 0.029. In the structure, strongly bonded linear uranyl cations UO2 2+ are equatorially coordinated by two O and three Cl atoms to form (UO2)Cl3O2 pentagonal bipyramids. Each bipyramid shares its O-O edge with an adjacent (NO3)? anion to form finite clusters with the chemical composition [(UO2)(NO3)Cl 3]2?. The Cs+ cations provide three-dimensional connectivity of the structure by forming Cs-O and Cs-Cl contacts to the uranyl nitrate chloride complexes. Related structures of mixed-ligand uranyl halides are compared.
