Poly[[tetraaquatris(mu(3)-2,2-dimethylmalonato)dilanthanum(III)] monohydrate].
In the title complex, {[La(2)(C(5)H(6)O(4))(3)(H(2)O)(4)].H(2)O}(n), the La atoms are connected by bridging O atoms from carboxylate groups to build, through centres of inversion, two-dimensional layers parallel to the ac plane containing decanuclear 20-membered rings. The coordinated water molecules are involved in intralayer hydrogen-bond interactions. Adjacent layers are linked via hydrogen bonding to the solvent water molecules. This work represents the first example of a new substituted malonate-lanthanide complex.
