摘要：

The holmium and europium complexes of the tetraanion of 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (H(4)DOTA), namely, sodium aqua(1,4,7, 10-tetraazacyclododecane-1,4,7, 10-tetraacetato)holmium(III) tetrahydrate, Na[Ho(C16H24N4O8)(H2O)]. 4H(2)O, and sodium aqua(1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetato)europium(III) tetrahydrate, Na[Eu(C16H24N4O8)(H2O)]. 4H(2)O, show nine-coordination around the metal ion, with a square antiprismatic coordination geometry involving four N- and four O-donor atoms of the DOTA ligand, and a coordinated water molecule in a capping position.
