A Novel Pillar-Layered Organic−Inorganic Hybrid Based on Lanthanide Polymer and Polyomolybdate Clusters: New Opportunity toward the Design and Synthesis of Porous Framework

An unprecedented microporous lanthanum polymolybdate, [{La(H 2 O) 5 (dipic)}{La(H 2 O)(dipic)}] 2 {Mo 8 O 26 }·10H 2 O (H 2 dipic = pyridine-2,6-dicarboxylic acid) 1, which is constructed from lanthanum−organic coordination polymer sheets pillared by individual octamolybdate clusters, is reported.
