By slow evaporation of solutions containing Ln(ClO4)(3) (Ln = Pr, Nd, Sm), H5IO6 and an excess of HCIO4, crystals of the title compounds could be obtained. Their structures were determined by single-crystal X-ray diffraction. The compounds crystallize in the monoclinic crystal system, space group I2/a. They contain two types of periodate ions: octahedral H4IO6 groups and two crystallographically different I2O10 groups. which consist of two edge-sharing octahedra. These anions coordinate to the canons as bridging groups yielding a three-dimensional network. Together with some water of crystallization, a coordination number of 9 is achieved around the lanthanide ions with a tri-capped trigonal prismatic geometry.
