On the formation of framework indium sulfides

Novel layered and open framework indium sulfide organic/inorganic hybrid materials have been synthesized via hydro- and solvo-thermal techniques. Considerable structural diversity within this family of compounds is realized through a variety of structural building units. DEA-InS-SB1 and -SB2 (both [(CH3CH2)(2)NH2](6)In10S18) consist of corner linked In10S20 supertetrahedra; DPA-InS-ML ([C6H16N](4)In4S10H4) contains isolated In4S10 thioanions, while TMDP-InS-SB4 ([C13H14N2](4)In9S17) has a layered structure containing linked In9S20 double adamantane clusters. Factors governing the formation of the structural building units (in the presence of amines) and their subsequent template mediated assembly are discussed with respect to previously reported and novel structure types.
