Synthesis and X-ray crystal determination of four novel lanthanide(III) oxydiacetate complexes
Four new lanthanide oxydiacetates [{Y(Hoda)3} · H2oda · H2O] (1), [{Y2(oda)3 (H2O)4 · 2H2O}n] (2), [{LaGd(oda)3(H2O)3 · 6H2O}n] (3) and [{LaY (oda)3(H2O)3 · 6H2O}n] (4) (oda = -O2CCH2OCH2CO2 -) have been synthesized and their structures determined by single-crystal X-ray methods. Compound 1 is monom...

| Sumario: | Four new lanthanide oxydiacetates [{Y(Hoda)3} · H2oda · H2O] (1), [{Y2(oda)3 (H2O)4 · 2H2O}n] (2), [{LaGd(oda)3(H2O)3 · 6H2O}n] (3) and [{LaY (oda)3(H2O)3 · 6H2O}n] (4) (oda = -O2CCH2OCH2CO2 -) have been synthesized and their structures determined by single-crystal X-ray methods. Compound 1 is monometallic with distorted YO9 units formed via coordination of three tridentate Hoda ligands. Compound 2 consists of polymeric sheets of YO9 units formed via coordination of three tridentate oda ligands bridged through carboxylate groups to YO8 units. Compounds 3 and 4 are isomorphous heterobimetallic three-dimensional networks of LnO9 units (Ln = Gd or Y) formed via coordination of three tridentate oda ligands bridged to the larger radius La(III) in LaO9 units through carboxylate groups. © 1998 Elsevier Science S.A.
