Abstract
Single crystals of [NpO2L(H2O)]·1/3H2O (I) and [PuO2L(H2O)]·H2O (II) (H2L — orthophthalic acid) have been synthesized, their structures have been determined by X-ray structural analysis. Actinide atoms in both compounds are seven-coordinated. The interaction between actinide dioxocations and phthalate anions results in formation of infinite tubes in I and layers in II. The structures are compared with those of other phthalate compounds of hexa- and pentavalent actinides, in particular, with the structure of [UO2L(H2O)]·H2O which differs from the structure II.
