On the formation of framework indium sulfides

Novel layered and open framework indium sulfide organic/inorganic hybrid ma terials have been synthesized via hydro- and solvo-thermal techniques. Cons iderable structural diversity within this family of compounds is realized t hrough 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, whi le TMDP-InS-SB4 ([C13H14N2](4)In9S17) has a layered structure containing li nked In9S20 double adamantane clusters. Factors governing the formation of the structural building units (in the presence of amines) and their subsequ ent template mediated assembly are discussed with respect to previously rep orted and novel structure types.
