Resumo

Bis-hexaaquasodium decaaqua-monohydrogen-hexasodium-gadolinium-bis-(nitrilo-tris-methylenephosphonate) tetrahydrate [Na(H2O)6]2[GdNa6H(H2O)10{N(CH2PO3}2]·4H2O (space group P21/c, Z = 2, a = 11.8168(7) Å, b = 10.5403(9) Å, c = 19.8094(10) Å, β = 94.232(5)) has been synthesized and isolated. The Gd3+ ion is coordinated in the configuration of an elongated rhombohedron in the environment of two acid residues {N(CH2PO3)3}. Two rhombohedron’s vertices distant from its center are occupied by nitrogen atoms, and six nearest vertices are occupied by oxygen atoms. Six sodium ions form inorganic bridges P-O-Na-O-P. The structure of the obtained complex is confirmed spectroscopically. XPS data indicate the formation of coordination bonds Gd-N and multiple bonds Gd-O.
