摘要：

The europium complex with pyridine-2,6-dicarboxylic acid forms three-dimensional polymers in the solid state. The crystal structure of this assembly shows that europium cation is nine-coordinated and the first coordination sphere contains four water molecules. Mono(dipicolinate) structural units are inter-connected by bridging carboxylate oxygens to provide a compact supramolecular structure with a high density. (C) 2009 Elsevier Ltd. All rights reserved.
