Catena-Poly[[[tetra-mu(2)-aqua-heptaaqua-(mu(2)-benzene-1,3,5-tricarboxylato)-mu(3)-hydroxido-trinickel(II)sodium]-mu(4)-benzene-1,3,5-tricarboxylato]sesqui-hydrate]

The title coordination polymer, {[Ni3Na(OH)(C9H3O6)(2)( H2O)(11)] center dot 1.5H(2)O}(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.
