Controlled Assembly of Zero-, One-, Two-, and Three-Dimensional Metal Chalcogenide Structures

A room-temperature solution route to the controlled synthesis of
0-, 1-, 2-, and 3-D assemblies of molecularly linked metal
chalcogenide clusters using essentially identical building blocks is
reported. The solvating, ligating, and reducing abilities of hydrazine
at room temperature have been exploited to simultaneously dissolve
metal chalcogenides and organize the resulting building blocks
into frameworks of increasing dimensionalities. Control of the
product dimensionality was achieved by varying the reactant ratios
and the amount of hydrazine solvent employed in the reaction.
The products have been characterized by single-crystal X-ray
diffraction, Raman spectroscopy, and magnetic susceptibility.
