“…Numerous artificial molecular recognition systems can be designed by incorporating complementary hydrogen bond donors and acceptors into host and guest molecules. [1][2][3][4][5][6][7][8] These artificial systems function as convenient and direct models to mimic complicated biological activities. Recently, these studies have been further expanded to the airwater interface.…”

The hydrogen-bonding network formed between a triaminotriazine amphiphile (2C 18 TAZ, 1) and complementary barbituric acid (BA, 2) at the air-water interface is investigated by polarization-modulated infrared reflection absorption spectroscopy (PM-IRRAS). The molecular structure and orientation of the 1:1 hydrogenbonding network at the air-water interface is revealed in this study. Without the addition of BA to the subphase, the NH 2 scissoring of 2C 18 TAZ appeared in the spectrum as a broad negative absorption band between 1660 and 1605 cm -1 , indicating its perpendicular orientation to the air-water interface. When BA was added to the subphase, the NH 2 scissoring absorption band from the triaminotriazine moiety disappeared due to the complementary hydrogen bonding of BA to the 2C 18 TAZ monolayer. The formation of the rigid 1:1 hydrogen-bonding network also resulted in the disappearance of one of the ring quadrant stretch absorption bands of the 2C 18 TAZ molecule. New bands which are attributed to the vibration of BA can be clearly seen. Particularly, the CdO stretch from BA shows up in the spectra as two negative absorption bands around 1700 cm -1 . The negative signature of these two bands suggests that the BA molecules are oriented in the hydrogen-bonding network with the C-2 carbonyl positioned vertically toward the air, and the C-4 and C-6 carbonyls directed into the water subphase. This is consistent with formation of an assembly which optimizes the use of complementary hydrogen bonding between two components. Furthermore, the effect of competitive polar organic solvents in subphase, such as DMSO, on the hydrogen-bonding network has also been observed in this study. Compared to the previous IRRAS studies on the similar monolayers, the sensitivity of PM-IRRAS is obviously improved. PM-IRRAS will likely become a powerful analytical technique for the characterization of molecular structure and orientation of Langmuir monolayers at the air-water interface.

“…James, Verspui, Spek & van Koten (1995) employed CCH...C1--Pt hydrogen bonds to create infinite chains in an organoplatinum compound. Munakata and coworkers prepared hydrogen-bonded copper(I) complexes with large channels occupied by cations, using the well known dimeric 2-pyridone synthon (Munakata, Wu, Yamamoto, Kuroda-Sowa & Maekawa, 1996). Dance and co-workers have made extensive use of the 'phenyl factor' (interactions between adjacent aromatic groups) in inorganic supramolecular chemistry.…”

The area broadly described as crystal engineering is currently expanding at a brisk pace. Imaginative schemes for supramolecular synthesis, and correlations between molecular structure, crystal packing and physical properties are presented in the literature with increasing regularity. In practice, crystal engineering can be many different things; synthesis, statistical analysis of structural data, ab initio calculations etc. Consequently, we have been provided with a new playing field where chemists from traditionally unconnected parts of the spectrum have exchanged ideas, defined goals and made creative contributions to further progress not only in crystal engineering, but also in other disciplines of chemistry. Crystal engineering is delineated by the nature and structural consequences of intermolecular forces, and the way in which such interactions are utilized for controlling the assembly of molecular building blocks into infinite architectures. Although it is important to acknowledge that a crystal structure is the result of a subtle balance between a multitude of non-covalent forces, this article will focus on design strategies based upon the hydrogen bond and will present a range of approaches that have relied on the directionality and selectivity of such interactions in the synthesis of predictable one-, twoand three-dimensional motifs.

“…A rapidly developing area in this field is the synthesis of extended inorganic structures, where the ability to control functionality along these networks is of much current interest [3,4]. Recently, weak intermolecular interactions, such as hydrogen bonding [5][6][7][8][9][10], as well as pÁÁÁp and C-HÁÁÁp interactions [11][12][13][14] are often used to construct networks from one-dimensional (1D) chains or two-dimensional (2D) sheets. But three-dimensional (3D) polymetallic supramolecular structures constructed from 1D chains through the presence of water clusters are seldom reported [15,16].…”

A novel layered supramolecular compound [Ni(L)(TPHA)]Á8H 2 O, containing two-dimensional (2D) water clusters and terephthalato-bridged ligand, where L = 1, 3,6,9,11,14-hexaazatricyclo[12.2.1.1 6,9 ] octadecane, TPHA = terephthalate dianion, has been synthesized and structurally characterized by spectroscopy and X-ray crystallography. The complex is neutral, in which the nickel(II) ions are bridged by the TPHA to form a one-dimensional (1D) infinite chain structure, and containing the eight-member water cluster. The presence of octameric water clusters have effectively increased the 1D coordination polymer to a threedimensional layered structure. Every water cluster is connected strongly by a O-HÁÁÁO hydrogen bond (range of the bonds between 2.724 and 3.056 Å ). The complex crystallizes in monoclinic, space group P21/c with a = 9.788(3), b = 13.030(4), c = 11.646(4) Å , and b = 104.551(5)°.
