heal.abstractIonic salts with the formulae {3[GBPMTU](+)center dot 3[X](-)center dot nH(2)O} (BPMTU = 1,3-bis(3-pyridylmethyl)- 2-thiourea, X = Cl(-) and n = 1.5 (1), X = Br(-) and n = 1 (2), X = I(-) and n = 1 (3)) were synthesized. The compounds have been characterized by elemental anaylses, TG-DTA, FT-IR, far-IR, Raman, ESI-MS and (1)H, (13)C-NMR spectroscopic methods, and X-ray powder diffraction techniques. The crystal structures of 1 and 2 have also been determined by X-ray diffraction at 120(2) and 100(2) K, respectively. In 1, weak 1p(Cl(-)) -> sigma*(O-H) hyperconjugative interactions and OH center dot center dot center dot Cl(-) hydrogen-bonding interactions lead to the formation of 1-D zigzag tetrameric complexes consisting of four chlorides bridged by four waters. Two oxygens of the bridging waters are also coordinated to Cl(-) of the complex forming a parallelogram-shaped ring. Two chlorides are also anchored by NH center dot center dot center dot Cl(-) hydrogen bonds in the free space between four tetrameric complexes. Heating 1 at 100 degrees C for 4 h does not remove lattice water and the framework structure is retained. In 2, NH center dot center dot center dot Br(-) hydrogen-bonding interactions stabilize the supramolecular architecture. In this case, however, only two bromides are bridged by one water through OH center dot center dot center dot Br(-) hydrogen bonds. The supramolecular interactions existing in the crystal packing of the ionic salts have been analyzed at the density functional theories and ab initio CCSD(T) levels of the theory.en
