Molecular self-assembly is the spontaneous association of molecules under equilibrium conditions into stable, structurally well-defined aggregates joined by noncovalent bonds. Molecular self-assembly is ubiquitous in biological systems and underlies the formation of a wide variety of complex biological structures. Understanding self-assembly and the associated noncovalent interactions that connect complementary interacting molecular surfaces in biological aggregates is a central concern in structural biochemistry. Self-assembly is also emerging as a new strategy in chemical synthesis, with the potential of generating nonbiological structures with dimensions of 1 to 10(2) nanometers (with molecular weights of 10(4) to 10(10) daltons). Structures in the upper part of this range of sizes are presently inaccessible through chemical synthesis, and the ability to prepare them would open a route to structures comparable in size (and perhaps complementary in function) to those that can be prepared by microlithography and other techniques of microfabrication.

Metal Complexes of Organophosphate Esters and Open-Framework Metal Phosphates: Synthesis, Structure, Transformations, and Applications

The title compound has been synthesized and its crystal structure determined at room temperature. Cd 2 (Sacch) 4 (Im) 4 , F.W. = 1225.83, monoclinic. Space group: C2/c, Z=4, a=20.065(3)1, A, b = 11.164(4) A, c = 20.697(6) A, β = 94.69(5)°, The coordination polyhedron of Cd(II) correspond to a five-coordinate trigonal-bipyramid. In the title complex, two of the saccharin groups act as monodentate ligands. The other two act as bidentate ligands. The two Cd(II) ions are bridged by the two bidentate saccharin groups and the distance is 4.75 A.

Photoacoustic spectra of o-sulphobenzoimide transition metal complexes

The d-d transition spectra of Cu(TTA)2 and Cu2(sacch)4(Im)4 complexes crystals have been determined. Using the crystal structure data, their d-d transition energy levels are calculated by the program which we used for the calculation of field theory. The calculated values are in good accordance with the experimental results. Compared to the copper(II) complexes in various coordination environments, their d-d transition spectra have an evident difference.

A distorted macrocycle was assembled from Cu(II) and 4,4‘-diaminodiphenylmethane, and a new maze-type two-dimensional network was constructed from macrocycles via hydrogen interactions.
