Three uranyl crotonate complexes with composition R UO 2 (C 3 H 5 COO) 3 [ R = K ( I ), Rb ( II ), Cs ( III )] were studied using FT‐IR spectroscopy and X‐ray diffraction analyses. The structures of I – III are constructed of typical anionic tris(carboxylato)uranylate complexes [UO 2 (C 3 H 5 COO) 3 ] – . Cubic crystals of I and II have 3D framework structure, whereas triclinic crystals of III have layered structure. In the structure of III uranyl ions are nonlinear and non equal‐arm due to uranyl‐cation UO 2 2+ –Cs + interactions. Nonlinear optical activity of noncentrosymmetric uranyl carboxylates was estimated by second harmonic generation measurements. Uranyl crotonate complexes show about twice higher SHG ability than uranyl butyrate and valerate complexes.
