- Аннотация: Three uranyl crotonate complexes with composition RUO2(C3H5COO)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 [UO2(C3H5COO)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 UO22+–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
