ChemInform Abstract: New Self-Assembled Structural Motifs in Coordination Chemistry

Polyoxometalates (POMs) are anionic molecular metal oxides with expansive diversity in terms of their composition, structure, nuclearity and charge. Within this vast collection of compounds are dominant structural motifs (POM...

A review of the coordination chemistry along with the structural features of heavy element complexes of dithiocarbimate di-anions in the form of [(R)C=NCS2]2− for R = CN, alkyl, and aryl are described. This class of compound is far less studied compared with the well-explored dithiocarbamate mono-anions formulated as [R(R’)NCS2]− for R/R’ = H, alkyl, and aryl. The coordination chemistry of dithiocarbimate di-anions is dominated by a S,S-chelating mode; rare examples of alternative modes of coordination are evident. When comparisons are available, the structural motifs adopted by metal dithiocarbimate complexes match those found for their dithiocarbamate analogs, with only small, non-systematic variations in the M–S bond lengths.

AbstractSelf-assembly chemistry is finding use as a means of controlling the nanoscale structures at materials interfaces. Building on the success of a previous methodology, Ruthenium porphyrins have been coordinated to the pyridine-terminated surface of a self-assembled alkylsilane coupling layer on silica glass. These arrays are built in a stepwise fashion in which the surface of each layer allows further reaction to yield the next layer. Characterization by UV-vis and XPS confirms the deposition of the alkyl chains and pyridine moieties of the coupling layer, as well as coordination of the subsequent Ru-porphyrin layer. AFM analysis indicates very smooth surfaces, with roughness measured at 0.43 nm and 1.43 nm for the pyridine and porphyrin layers, respectively. The occasional appearance of large surface features (15-30 nm diameter) suggests aggregation among Φ-systems, with further characterization underway. Strategies toward the construction of a multilayer porphyrin architecture are also reported.
