    Abstract: The crystal of dimethyl sulphoxide complex of yttrium [Y(NO33·3DMSO] belongs to the monoclinic system, α= 13.604(4)?, b= 12.669(4)?, c= 11.554(2)?, β= 100.14(4)° and Z=4. The space group is P21/n. The diffraction data were collected using PW-1100 four-circle diffractometer. The number of independent diffraction data amounts to 3615. The structure was solved by heavy-atom method. Structure parameters were refined by full matrix and block diagonal least square method to a final R = 0.080. The result of structure analysis establishes that the polyhedral coordination of " three-headger triprism" is formed by nine oxygen atoms surrounding the Y cation. The distances between the yttrium and the coordinating oxygens are Y-ODMSO = 2.285?, Y-ONO3-= 2.460?.

    Abstract: The crystal of potassium lanthanum metaphosphate with composition KLa[PO3]4 belongs to monoclinic system. The space gr oup is P21 with lattice parameters α= 8.106(3)?, b= 8.551 (2)?, c = 7.326(3)?, β = 92.18(6)°. Two molecules are contained in the unit cell. A fullmatrix, least square refinement gave R=0.061, Rw = 0.062 for 1026 independent reflections. The basic structural units are helical ribbons, (PO3)n, formed by cornersharing tetrahedra of PO4. The LaO8 dodecahedra are isolated without sharing any O atom with each other, and K atom locate on the center of irregular interstitial polyhedra. The shorhest La-La distance is 7.063?.
