摘要

The coordination compounds of Er3+ with 1-(methoxydiphenylphosphoryl)-2-diphenylphosphorylbenzene [ErL21(NO3)(2)](2)[Er(NO3)(2)(H2O)(5)](0.333)(NO3)(2.333) center dot 2.833H(2)O (I) and its ethyl substituted derivative [ErL22(NO3)(2)][Er(NO3)(5)](0.5) center dot 0.5H(2)O (II) are synthesized and their crystal structures are studied. I and II contain [ErL2(NO3)(2)](+) complex cations of identical composition and close structure. The eight-vertex polyhedron of the Er atom in the shape of a distorted octahedron with two split trans vertices is formed by the O atoms of the phosphoryl groups of L ligands and nitrate anions. L ligands close nine-membered metallocycles. The structures contain spacious channels which are populated differently, namely, by disordered [Er(NO3)(2)(H2O)(5)](+) complex cations, NO3- anions, and crystallization water molecules in I and disordered [Er(NO3)(5)](2-) complex anions and crystallization water molecules in II. The IR spectra of I and II are studied.
