Synthesis and structure of three molecular arylindium phosphinates

Reported here are the syntheses and molecular structures of three novel arylindium phosphinates, [(2,6- Mes2 C6 H3 In)2(OH)2(O2 PMe2)2] (1), [(2,6-Mes2 C6 H3 In)2(OH)(O2 PPh2)3] (2), and [(2,6-Mes2 C6 H3 In)(O2 PMe5 C3 H)2(H2 O)2] (3), which were obtained by condensation reaction of the m-terphenylindium dihydroxide [(2,6-Mes2 C6 H3 In(OH)2]4 with dimethylphosphinic acid, diphenylphosphinic acid, and 2,2,3,4,4-pentamethylphosphetanic acid, respectively.
