metal-organic compounds
The new heterobimetallic complex [{LaEu(oda)3(H2O)3·5H2O}n] (oda = −O2CCH2OCH2CO2−) has been synthesized and structurally characterized. Three tridentate oda ligands are coordinated to the smaller EuIII cation, whereas six adjacent outer carboxylate O atoms and three metal-bound water O atoms are bonded to the larger LaIII cation. The structure consists of a three-dimensional network with the metal centers bridged by oda carboxylate groups with EuLa separations of 6.95 (1) Å.
