Abstract

Novel supramolecular networks of 2D {[Ni(cyclam)][C6Hg- (COOH)2(COO)]2}n (1) and 3D {[Ni(cyclam)][C6H3(OH)2- (COO)]2}n (2) have been constructed by the self-assembly of [Ni(cyclam)](ClO4)2 with cis, cis-1,3,5-cyclohexanetricarboxylic acid (H3CTC) and 3,5-dihydroxybenzoic acid (HDHB), respectively, in py/MeCN/H2O. In the crystal structure of 1, each nickel(II) macrocyclic complex binds two H2CTC- ions at the axial sites. The coordinated H2CTC- ions form hydrogen bonds with one another, which results in organic bilayers having macrocyclic complexes as pillars. In the crystal structure of 2, each nickel(II) macrocyclic complex binds two DHB- ions in the trans position. Two free hydroxyl groups and one carbonyl oxygen atom of the coordinated DHB- ion are extensively hydrogen-bonded with the DHB- ligand of the neighboring complexes, which results in a 3D network where 2D organic layers are linked by the macrocyclic complexes acting as pillars.
