Two extended coordination frameworks of CdII-squarate complexes with the formulas [Cd2(C4O4) 2.5(H2O)4](dpaH)¡¤ 1.5(H2O) (1) and [Cd(C4O4)(dpa)(H2O)] (2) (dpa = 2,2?-dipyridylamine) have been synthesized under hydrothermal conditions and characterized by single-crystal X-ray diffraction studies. Structural determination reveals that compound 1 consists of a free monoprotonated 2,2?-dipyridylamine ion (dpaH+) and a two-dimensional (2D) anionic, layered framework, {[Cd2(C4O4) 2.5(H2O)4]-}, which is formed with two anti-prismatic square-boxes as the fundamental building unit through the connection between CdII ions and hybrid mu1,2,3-, mu1,2,3,4-squarates. Each square-box acts as a host for the inclusion of one pyridine ring of dpaH+. Adjacent dpaH+ cations are then self-assembled by the parallel alignment of the other pyridine ring of dpaH+ to complete a 3D network with one-dimensional (1D) channels intercalated by water molecules. Compound 2 contains a distorted octahedral CdII center coordinated by two squarates, two waters and one dpa ligand to form a 1D 2-legged, ladder-like framework by the connection of a [Cd(dpa)(mu2-H2O)]24+ dimeric unit and a mu1,2-squarate. Weak pi-pi stacking interaction and hydrogen bonds of N-H…O, O-H…O and C-H…O among the squarate, water and dpa ligands provide additional intra- and intermolecular interactions on the stabilization of these two polymeric frameworks.
