  The first suberate lanthanum(III) complex without uncoordinated water

  摘要：

  catena-Poly[[aqualanthanum(III)]-mu-(8-carboxyoctanoato)-mu-octanedioato], [La(C8H12O4)(C8H13O4)(H2O)](n), is, to our knowledge, the first reported rare-earth complex containing a flexible long-chain ligand that crystallizes without water of crystallization. The layered polymeric structure is built from infinite chains of one-edge-sharing LaO8(H2O) polyhedra, connected through the carbon backbone chains of the ligands. The two chemically different ligands act in the same coordination modes, exhibiting chelating bonds and mu-1,1-bridging monodentate linkage, and adopting the same extended conformation. In the relatively limited hydrogen-bonding network, a very strong hydrogen bond between the deprotonated and protonated ligand ends stabilizes the framework.
