Abstract: The title coordination polymer, {[Ni₃Na(OH)(C₉H₃O₆)₂(H₂O)₁₁]·1.5H₂O}_n, is built up from three independent Ni^II ions and one Na^I cation bridged by benzene-2,4,6-tricarboxylate (BTC) ligands and water molecules. Three Ni^II ions are bridged by three bidentate carboxylate groups of three BTC ligands, two aqua ligands and one OH^- unit, to form a trinuclear metal cluster. The Na^I cation is bonded to the Ni^II cluster by two bridging water molecules. One of the three BTC ligands bridges neighbouring clusters into one-dimensional chains, which are further connected through a complex hydrogen-bonding scheme, forming a three-dimensional suprastructure. The title complex is isomorphous with the previously reported Co^II complex.
