Featured researches published by Wakgari Hirpo.


Journal of The Chemical Society, Chemical Communications | 1992

Synthesis and structure of the first indium–copper cluster, [Cu6In3(SEt)16]– and its possible relevance to CuInS2

Wakgari Hirpo; Sandeep Dhingra; Mercouri G. Kanatzidis

The cluster (Ph4P)[Cu6In3(SEt)16] has been prepared by the reaction of [Cu(CH3CN)4]PF6 with (Ph4P)[In(SEt)4] and its crystal structure shows an adamantoid framework.


Polyhedron | 1994

Synthesis and characterization of indium thiolates: structures of [Ph4P][In(SBut)4·CH3OH and [Ph4P][In(SCH2CH2S)2]

Wakgari Hirpo; Anthony C. Sutorik; Sandeep Dhingra; Mercouri G. Kanatzidis

Abstract Reaction of InCl3 with four equivalents of KSBut in the presence of Ph4PCl gave the monomeric complex [Ph4P][In(SBut)4·CH3OH (1) which crystallized from methanol as colourless hexagonal shaped crystals. Reaction of InCl3 with NaSCH2CH2SNa and Ph4PBr gave [Ph4P][In(SCH2CH2S)2] (2), which readily crystallized from CH3CN as colourless crystals. Both 1 and 2 were shown by X-ray structures to have tetrahedral coordination of indium.
